QTP / Office Incompatibility
Just over last weekend, I noticed suddenly 3 of my test machines have problem launching ms office.
After some investigation, it only happens when QTP is launched. I believe it has nothing to do with OS or MS version because some of them are Win XP/7 and some of them are Office 2007/2010. So, the combination is mixed.
(1) When QTP is launched, Excel / Word / Powerpoint can't launch. I can see the process running in task mgr but it fail to appear in the window.
(2) When QTP is closed, Excel / Word / Powerpoint can launch normally.
* I managed to resolve the issue by reinstalling QTP.
Did you guys encounter incident like this before?... My QTP has been installed for more than 2 years and it just happened in a sudden. Another thing to note, it only happened to some of the test machines, 4 other machines are fine.
Re: QTP / Office Incompatibility
I believe, this is because some patchs were installed specielly on your windows 7 machine with office 2007/2010. You can check the same by going into control panel -> Programs and Features.
