Biggest glaring thing I see is the version of Perl, right now we push 5.12.3 in all of our builds and installers because of the issues that can occur through the Perl API otherwise. We've pretty much been version locked at that x86 lib for the longest time at least as far as Windows is concerned.
I've also noticed we have the wrong version posted on our ground up install which needs to change.
The best frame of reference is here:

We also officially support x86 for Windows, there is no real need to be using x64 across the board and can cause stability issues and inconsistencies in weird places that can leave you to be troubleshooting for sometime without any clear indication of what is actually going wrong (Seg faults or otherwise)
