this is not a valid Win32 App

I have read the post about this but still can't find s solution? I have originals(not copies) of several CDs, but when I try to run them I come up with the same message. I am using 2 computers 1/ Running Windows 7 and 1/ running Windows XP both completely up to date, could someone please give me some advice as it is driving around the twist (and it's not that ar) any help would be appreciated

g'day les_n

it could be possible that the disk may have some light scratches on them that could be causing the problem.have you tried making a new copy of the disks this may help recover the data on them.

 

Thanks for the hint but alas I tried that before bugging you guys
Thanks Again

 

if this has only just started since you updated to sp3 on the xp machine maybe rolling back the drivers for the cd/dvd rom might help is it happening with just a few cd,s or all
