Unfortunately such would not be legal any-longer. AutoDesk no longer has authorization to distribute VBA6, they now only have VBA7 which is only compatible with ACad 2014 (I think that's a prerequisite from MicroSoft to encourage use of newer tools through enforcing distributers to only give out new stuff). I'm not sure, but I think this means even if you've already downloaded the enabler previously, it's not strictly legal to install it now. I might be wrong about this though, I've not seen ADesk's licensing agreement with Microsoft on this.
Anyhow, you can always do a search on "autocad 2013 vba enabler".
This does sound like a big problem though. If I had lots of VBA stuff, I'd be converting them to Lisp or DotNet ASAP.
