yep i know where the dll's are but this does not help me.

i have just tried (in Qt Creator) to open a .pro file.

when i tried to build it i got the error message


No valid Qt version set. Set one in Tools/Options
Error while building project findfiles
When executing build step 'QMake'
Canceled build.

so nothing much at all works.

might just try deleting eveything and re-installing. failing that i might go back to to 4.4.3
