PS Elements 9-log file?

I installed a copy of Photoshop Elements 9 from a disk onto my Vista 64 operating system computer.  I later removed it to see if it was conflicting with my new Epson Perfection V500 photo scanner that I could not get to work.  I installed the PS Elements software and the scanner software onto an old Windows xp computer to see it would work. (It could).  Now I want to reinstall the PS Elements 9 on my Vista 64 os computer because that is where I want to use it.  But I can't, am getting the message "error opening installation file.  Verify that the specified log file location exists and is writable."  Exactly what log file would they be referring to?  And is there a solution? Thanks
