error during startup passmark with -p key

[iron3k]

I had V6 installed and then installed V7
Then uninstalled V6 and V7 and re-install only V7, I still have the same message if I try to run with -p command line parameter:

Error during startup. A problem has occurred with your installation.
You may need to uninstall and reinstall the software.

BurnInTest can't find a file that should be installed on the system with the installer. Did you install BurnInTest on the systems main disk, or a USB driver? Do you get the problem if you don't use the "-p" command line parameter?
