Didn't see this in the FAQ(hope I didn't miss it)

I have a user that needs Acrobat 6 on her PC. ( Wintel box running
NT4 SP6 all current patches)We bought her a copy of 6 but when it tries to install it pops up with a "Entry point not found" error." "The procedure entry point LCIWodCreatA could not be located in the dynamic link library MSVFW32.dll"
However, if I download a self extracting .exe trial version of
Acrobat from your site, it installs and runs just fine.
.....any tips on what might be going on would be appreciated.

Thanks!
