Just interested to know if there is a reason not to upgrade Office to 64-bit. The only reason I have not done it is the limitation of Sage EIR being 32-bit only.

I gather this is no longer an issue

Correct. The only reason we would not have recommended switching to 64 bit Office prior to v30 is because some features of Accounts such as EIR would not work. Now it is entirely up to you which variant of Office you use, we'd just recommend installing the same 'bitness' of Accounts, but even if there is a mismatch, most of the functionality, including EIR, should work

We've tried hard to make sure that nothing is broken if you have a reason to stick with 32 bit Office but Microsoft have been pushing 64 bit Office for a good while now so best to move to that if you are able to.
