It get's a bit complicated, bear with me
.
I have an IDE drive (windows) and a SATA drive (linux) . I had a partition set aside on the SATA drive because my Windows drive is so tiny. I just reinstalled linux, and formatted the drive. I didn't think that formatting a few games would be a problem, but it was.
Whenever I try to reinstall, it asks to repair. But it fails with an error. Originally it was a 'path has an illegal character' because windows reorganized the drive letters after the format, I fixed that with regedit. But now it gets a bit further and says:
"The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2343."
I'm guessing that the solution is to go through regedit and delete some links in there. But I barely know enough about regedit to modify drive names (if this were linux I could fix it, but windows is crazy
) .
