Whenever I try to open 'Object Repository' I am getting the error message, "This operation cannot be performed. For further help contact support".

After recoding a test, on selecting an object and right-clicking in QTP, I am able to view the object description, but if I select "View in Object Repository" nothing happens. So when I tried from menu/Ctrl+R, I am getting the above error message.

Any idea whether I need to install a patch or something?

I am at client location hence un-installing and re-installing might take a long time. So kindly suggest some option other than un-installation.
