Anyone else have trouble getting 10.2.600.26 to install? Mine keeps hanging at “Expanding Web Access Complete”
Are you using Manage Engine?
If so I have ran into this issue before its really weird, but even if not enabled Manage Engine will briefly inspect all the exe’s that get moved around your system just long enough to cause a File Locking Issue.
Only solution is to go and disable the manage engine service or … erm… take more drastic measures
We chose approach number 2
BTW this will also bite you when doing an automatic update if the Epicor.exe (or an exe) was touched which is how we found it.
