I'm having an odd problem.
I have a number of databases developed with access 2013 and saved in that format.
On my development PC all of these run perfectly well.
In the real location there is one PC with a full copy of access and a number of other new PC's with the runtime access (downloaded from Microsoft) installed.
Most of these databases run in the real location, one however is giving problems. (As usual, the most complex and most often used = Murphy's law in operation). It seems to run reliably on the PC with the full version of access but on the other PC's it sometimes runs for a short while and then fails with an error message such as 'Unknown function Date...' or 'Unknown Function Left...'
The most obvious difference is the runtime version of access in use and I have thought maybe one is 32 bit and the other 64 bit.
So how can I determine which type, 32 or 64, bit version of Access is in operation?
