 <p>Manu,</p> <p>You <em>can</em> use VBScript templates (thought it is a good idea to start moving off this platform anyway) in your CMS backend and 64-bit on the front end, if your front end is .NET or Java.</p> <p>What you cannot do is use COM on the Front-end (even if being called from .NET) and be on 64 bit, since the Tridion COM-based linking API is 32 bit only.</p> <p>The .NET linking libraries and the Java linking libraries are 32 and 64 bit compatible, but not the COM libraries.</p> <p>Hope this helps</p> <p>N</p>
