Is your installation of QTP causing any of the following weird behavior:
- Blue Screen of Death
- QTP hangs when you try starting or closing it
- QTP hangs when using text recognition methods
- On a 64-bit OS the QTP report contains the error “driver cannot be loaded and needs to be updated for 64-bits”
If so before throwing your computer out the window, or sticking your HP voodoo doll with pins, try this quick fix first.
Possible reason for this QTP Crashing Behavior
Sometimes an older system driver pal_drv.sys, that was developed for old text recognition mechanism that is no longer supported, can cause these odd behaviors.
Possible fix for QTP Crash
- Open a command prompt (Start > Run > type “cmd” > “Ok”)
- Navigate to “/bin” directory (for example: “cd C:\Program Files\HP\QuickTest Professional”)
- Run the following command:nt_tr.exe -remove
- Reboot the machine.
Give it a try
This doesn't always fix these odd issues, but it doesn't hurt to give it a try
Hi Joe,
I find your site very useful..Thank you for sharing your valuable knowledge.
I am working on QTP 11. When I run multiple scripts from HP ALM(QC) 11, the 1st script runs fine,2nd script status is ”Unable to open the testname> test”..from 3rd script, all has the below status “Unable to open the test in the testing tool”.
The execution log for script 2 is shown as “Unable to open the ” test.
Error from QuickTest Professional: Element not found..”. The execution log for all scripts frpm script 3 is shown as “Unable to open the test in the testing tool.
Error from QuickTest Professional: Cannot retrieve object..”
I can run these scripts 1 by 1 from QC successfully. This issue happens only when i try to run more than 1 script from QC. The most confusing part is that till last week, they were getting executed without any such issue and as far as I know nothing is updated in QC or QTP. I reinstalled the remote agent and QC/QTP add-ins. Still the issue persists.
Any light you could shed on this will be much appreciated.
Thanks, Neenu
Neenu » Thanks Neenu! Not sure why this is happening – does this behavior happen for all lab machines?
HI Joe,
I am getting the error “Unable to open test in the testing tool.Error from QuickTest Professional: Cannot retrieve object..”
This error is associated with few scripts when i tried to run from qc rest of them is working fine. I tried on all the lab machines, still have the same problem.
Details are following:-
1. OS:- Windows XP/Vista/Windows7
2. QC:- Component Build
OTA Client 10.0.0.2154
User Interface 10.0.0.2154
WebGate Client 10.0.0.2154

Execution Flow 10.0.0.2154
Site Administration Client 10.0.0.2154
HP Quality Center 10.00 Enterprise Edition
QTP:- QTP 11
We used to run the scripts from Remote desktop through citrix.
Hope you understand my issue. Please let me know if more clarification is required.
Thanks and Regards
Vineet
Vineet » Hi Vineet not sure about this one sounds like a QTP QC connection issue – or all machines on same domain? I usually see the “Unable to open test in the testing tool” error when the QTP machine does not have the “Allow other HP products to run tests and componets” selected but if that was your issue you would not be able to run any tests on that machine.
Hi,
QTP was freezing for me when opening scripts in Windows 7 32-bit so I tried your suggested “nt_tr.exe -remove” command. Now, the I can’t get the menu bar back. Even if I right-click and select “Customize -> Toolbars -> Restore All”. I can’t even check-off the “Menu Bar” option.
Please help,
Thanks
Mike » Have you tired doing a repair on your install?
Hi Joe,
Thanks for all fixes and suggestion on QTP. I need your help to understand why QTP 10 is hanging when I save new script or edited script. It wouldn’t as for file path to save or change not saved. completely QTP paralyzed. May I ask you what can I do to fix this issue.
environment details
– Windows 7 prof 32 bit
– QTP 10
– IE 8
Hi Joe,
QTP 11 is recognizing swfEdit as Edit box, swfButton as Button whereas UFT 11.5 is recognizing them as only swfObject for the same application. I am not sure what I am missing and why UFT 11.5 is recognizing as swfObject.
It would be great if I get your help please.
Thank you very much.

Hi Joe,
Thanks a lot for all the advice, its really helpful !!
Joe, i am running suite of around 1500 test cases on different OS (XP,7) without use of QC (I am using different File system to get which runs to be made).
But in this process QTP either stops working / Explorer.exe hangs / JIT debugger appears only in XP machines both (Machines / VM’s) also on
Where as everything runs smoothly on Windows 7 professional both is desktops/ VM’s
Solutions tried:-
1. I tried restarting QTP after a particular module with mercury object. Restart QTP and continue with remaining modules of the suite (But still the suite hangs in between on XP)
Please letme know if there are patch rolled out by HP to fix these or any other solutions
Thanks

hi.
when i tried to run QTP as administrator then my application run successfully , but when i open QTP directly by double click , then my system get crash, why it happen?
plz help me for this issue
Do you get any error messages? I have not seen this behavior before
Hi sir.
No there isn’t any error. let i explain you exactly what happen?
i worked on both web and desktop application, when i tried to run QTP as administrator then it works only on web application and script is created successfully, but when i tried same on desktop application script is not generated.
In other hand when i open QTP directly by double click, it works only on Desktop application and script is created successfully but after some time all application get crashed.
If you run a Repair on QTP does it resolve this issue? Do you have local admin rights on your machine?
HI JOE
YA, it may be a point, i work for an IT organisation, there are some restriction on my PC, Do you think it happen only, becoz of admin rights issue?
Hi,
Please any workaround.
I am using UFT 11.52 and facing some issues.
1. Hangs while adding objects to OR
2.Hanging while highlighting objects from rep.
3.While spying objects it gets hanged
Do you have patch 1 installed for UFT 11.52:
Hi Joe
we are facing a strange issue. there are some objects in our application on which if we try to do object spy or try to add objects in OR, system hangs
also, on Object spy on some other objects > all the properties and corresponding values are displayed properly in the Object Spy dialog
but when we try to add this object in OR no property and values are displayed for this object in OR and object is not adding in the OR.
Environment: .NET 4.0, wpf application, QTP 11, Windows 7, 64 bit machines
Pls reply and suggest how this issue can be resolved
Hi Amit,
Not sure – I have seen some spy freezes resolved by disabling the enhanced object spy features in the registry.
You can disable the enhanced Object Spy features by adding the following registry entries. This will disable the advanced features added with the QTP 9.5/UFT 11.5 and above releases:
HKEY_CURRENT_USER/Software/Mercury Interactive/QuickTest Professional/MicTest/DisableObjectsHighlight =dword:00000001
HKEY_CURRENT_USER/Software/Mercury Interactive/QuickTest Professional/MicTest/DisableSpyEnhancement=dword:00000001
Please let me know if this helps you.
Hi Joe,
I’ve encountered a similiar problem to the one Neenu mentioned.
When i try to run an automatic test from QC i get this error:
Unable to open the ‘Create User’ test.
Error from QuickTest Professional: Test not found..
I tried to run the same test (from same test set) from a different computer and it worked…
Do you have any suggestions?
Thanks,
Mor
Do you have both the HP Quality Center Connectivity and the QTP add-in installed on the machine giving you an issue?
Hi Joe,
I am using QTP 10 on windows XP. I have a problem that whenever I try to open a previously saved test, QTP crashes. I cannot work further. I tries your cmd method of ‘nt_tr.exe -remove’, but its showing command not recognized.
Could you please help.
Thanx
I have not seen this issue before. I did find the following suggestion from itelearn . Does it help you?
pal_drv.sys is a system driver that may cause frequent QTP crashes. Try to follow below steps, it may help you
Uninstall pal_drv:
%ProgramFiles%\hp\QuickTest Professional\bin\nt_tr.exe /UNREGSERVER
Install pal_drv:
%ProgramFiles%\hp\QuickTest Professional\bin\nt_tr.exe /REGSERVER
Joe,
I did run this command ‘nt_tr.exe -remove’ in cmd, and message came that ‘Test recognition has been installed successfully’. I then reboot my machine, but still there is the same problem.
I am facing with the same issue as the one Gurjinder mentioned ”
when i tried to run QTP as administrator then my application run successfully , but when i open QTP directly by double click , then my system get crash, why it happen?”
I haven’t found a solution yet but try:
1.Closing All the Browsers before opening QTP.
2.Right click QTP icon and ‘Run as Administrator’
Thanks
Here’s a question for you:
Related to QTP 11.0, Windows XP and Windows 7
Sometimes when QTP has been running for a while, it goes “stoopid”. It cannot see objects that it has been working with all day forcing me to restart the software, and often cannot save my edited tests. It seems to get lost in the Do-loops and If-Then statements, telling me that I’m missing an End If, or have a Loop without a Do.
I look at the line number referenced, and there’s usually nothing wrong. If I try then to run the test, the error message returns but now shows one or two lines of code that QTP apparently changed or saved incorrectly.
That is; there may be two Wait statements in a row instead of the lines that I wrote as If-Then, and Wait. Or it might add an extra End If statment. In other words, it randomly replaces lines of code with adjacent lines.
I live in fear that QTP is really going to booger something up!
I doubt that the issue is patch-related. We keep our systems fully up-to-date. I’ll give you a dollar if you can figure this one out!
Hi Jeff – I have seen odd issues on our QTP execution VM but can never track down the root cause. Basically we have a job that reboots the machines every night and we also reboot after long test runs to avoid these type of issues.
I am using QTP 11,all the scripts are running successfully. After windows update, not able to execute the scripts. That means if I Run the scripts, it shows running only but no action takes place. I cannot stop QTP scripts also, need to stop forcibly using task manager.
Tried uninstalling QTP,Registry cleanup…but no success.
Kindly help me resolve this issue.
What should be done if we need to keep qtp execution on going when qtp execution is hung up on that machine for unlimited time? I mean we can’t even invoke recovery scenario of qtp here as qtp itself got hung up and caused machine to hung up for unlimited time?
> I do not want to restart the machine here
> I want to break the execution here
Are you running your tests from ALM/QC?
Joe
I have scripts in QTP11 now we have upgraded to UFT12.2 so scripts created in QTP11 when I tried to run in UFT12.2 it is not running and we are using SAP application. Could you please help me on this issue?
Are you getting any errors?
Hi Joe,
I have test to open application in a browser which i call in different tests to open browser and launch application. Test was working fine but now browser is closing after execution of the test. I am using UFT 12.54.
I think there should be an agent on the machine that has a setting if you want to close the browser or leave open. Have you looked to see what that is set to?
