Alternatives to formatting HD and reinstalling Vista

I have a Vista Premium PC where I installed a trial version of a program,
let it expire and now I bought the full version but cannot seem to get it to
install since the ghost of the old trial version seems to be haunting my PC.

Before I start formatting the drive (and lose all my other programs and
settings) and attempt to reinstall Vista, I was wondering whether there was
some easy way to wipe all traces of the trial program? I am no great tech
expert, so protracted brain surgery with registry settings may not be an
option for me!

And what application might this be?

We do not have left over installs in Linux.
