I am still having this problem with 10.0.1 upgrade pre check from 9.5.13 on Windows Server 2016. I would have thought this would have been fixed by now.
Are they instructions for running the pre check manually?
I ran the upgrade manually from:
C:\Program Files (x86)\BigFix Enterprise\BES Client__BESData\BES Support\__Local\PreCheck.
The command-line is:
BESAdmin.exe /username=domain\userid /passwordencoded=password /preupgrade /standalone /hideui
If you ran the fixlet in the console, the PreCheck Directory and BESAdmin.exe will have been created.
The output from running the pre check manually is: \Bigfix Enterprise\BES Server\preupgrade.out.
Then I ran the fixlet again, and it still failed.
