QTP Crashes Hangs Freezes Frequently

Spread the love

Few days back i got a comment from one of my unknown reader regarding QTP crashes or freezes frequently while running test batch runner. “In case your QTP crashes frequently” there is a solution given in Ankur’s blog..
I am echoing the same…

A tip submitted by LearnQTP reader Ajay Mohan.

pal_drv.sys is the system driver that may be the culprit for your frequent QTP crash issues. This driver was developed for text recognition mechanism that QTP doesn’t support now. To solve the QTP crash problem, you need to uninstall this driver and here is how:

Go To command prompt. [Start > Run > Type cmd]

Change directory to C:Program FilesHPQuickTest Professionalbin using the command

cd C:Program FilesHPQuickTest Professionalbin

Type in nt_tr.exe –remove as shown in the image below.

You will see a message box stating Text recognition has been uninstalled.

Reboot machine. It should work without reboot as well but just in case.

Try opening QTP, it should no longer crash now.

Even i learnt this nice solution…credit goes to ankur and Ajay.

  1. I am encountering this issue during insertion of checkpoints. I haven’t tried your solution yet, since I don’t think this is caused by the text recognition. Can you please help? Thank you
