Excel 2013 - "There was a problem sending the command to the program"
I've just installed Office 2013 on a couple of new terminal servers. There is an issue that effects a few users. When these users try to open an Excel file directly through Explorer, it comes up with an error that says "There was a problem sending the command to the program". If Excel is open at the time, the file will open.
Naturally I've googled this and followed the various suggestions. The most common one is to disable "Ignore other applications that use DDE" but that's already disabled. I've also tried the various registry hacks suggested but none of those work either.
This is only affecting a few users, me among them, which is all the more infuriating. It seems to follow me from one machine to another as well so I assumed that it was a roaming issue but deleting the UE-V settings package for Office 2013 and deleting local user profiles from the machines made no difference.
I'm getting annoyed with this one, can anyone help?
