Access 2010 project. Works fine in Access and the runtime on every machine except one. Problem is that the one machine is the Remote Desktop server (Windows Server 2008 64-Bit)! All been working ok on the server until recently and I now get a bunch of errors when the program loads. These are all run-time (such as form loading issues and the dreaded "Expression may not result in the name of an object...." and not VBA related - most errors are "Type Mismatch" but I do get other problems. 80% of the program still works. Older complied .ade files still work on the server. Nothing special has changed in the source code since the working and non-working versions, and the newest ones work fine on any other PC running the same 2010 runtime. I have applied all Windows & Office updates to the Remote Desktop server, re-installed Access Runtime from scratch and run a code comparison to find all the VBA differences between working and non-working versions. No new references have been added (I did try removing and re-adding some but no effect). I found an MS article saying that a DAO reference had to come before ActiveX (ADO) - I have both in my program but there were already in the correct order. Short of reverting everyone back to the old version and rebuilding the changes one by one I cannot see how to fix this other than leaving Remote Desktop users running the old version and they will never get new features. I feel this started when MS updates were applied to the Remote Desktop server but there are hundreds of them and I can't back them all out to find this one issue. Any thoughts gratefully appreciated!
