Clearing the cache in Epicor menu doesn’t always clear it all. We’ve had to
clear the cache manually in the folder, path is usually similar to:
C:\ProgramData\Epicor*(Epicor-Server)*-808(number sequence)(ID)\CustomDLLs
Besides the variables noted above, the -808 could be a different number
sequence, it’s what we get in our environment.
You can Move/Rename the -808 directory and it’ll recreate it or just find
the DLL in question in the CustomDLLs folder and delete it.
