MS SQL Server 2016 SP3 upgrade failing
I tried to apply the SP3 on one of my SQL Server 2016 DB server, and it kept failing with the below error.
Error description: The installer has encountered an unexpected error. The error code is 2203. Database: C:\WINDOWS\Installer\inprogressinstallinfo.ipi. Cannot open database file. System error -2147286928
After trying several things, finally this worked for me: I renamed the existing C:\Temp folder to C:\Temp_old and created a new Temp folder in the C drive.
