I built my own test environment: Server 2012 R2 Standard, installed SQL 2012 SP1 Express and added WSUS Role. SQL installed without any problem. I did try using SQL 2012 SP1 plus CU3 and got the same error message, when I try to configure WSUS
Complete WSUS Installation
DB instance: WSUSServerName\WSUS
Store update locally: C:\WSUS_Updates
Click Run, I got MMC has stopped working, Check online for a solution, Close the program, Debug the program.
Any idea? Thanks.
