Hi Magic
Although my experience with S3D tool is only limited, to answer your questions.
Yes it works fine with win7 64
If you have any problems just install it outside c:/program files(x86)
(Alternatively just turn off UDC and you'll never have a problem again)
The link in Plissken 04 (Maik) ftp downloads section is fine for both 32 and 64 bit OS's
ftp://maikhaas.dyndns.org/Volume_1/S...ODS/SKWASJAER/
Hope this helps mate.
Best regards.
