IT Advice: Run wrapper.exe ?????

I keep trying to run a cd-rom that used to run on my XP system.
Now I bung it in the tray on my Vista machine and I get an error type box
” Run wrapper.exe.
Publisher not specified…..”
and it won’t run!

I have contacted the publisher, but you never know with IT areas, some are brillaint, others take for ages to come back.
Is there anything simple and legal I can do?
cheers
Q

er, change back to XP?
