Got this vague message during SRM 5.0 install: “The provided database version is not supported. Please enter a supported database.”. Thought it was referring to the version of the database server (SQL Server) which was supported. Dug in to the installer log file (Example: C:\Users\\AppData\Local\Temp\3) and found the following lines:

VMware: Srm::Installation::Database::CheckDsn: INFORMATION: Validating DB type: SQL Server
VMware: Srm::Installation::Database::CheckDsn: INFORMATION: Successfully connected to database.
VMware: Srm::Installation::Database::CheckDbPopulatedAndNeedsUpgrade: INFORMATION: Database already contains product tables.
VMware: Srm::Installation::Database::CheckDbPopulatedAndNeedsUpgrade: INFORMATION: Database version: ‘4.0.0’
VMware: Srm::Installation::Utility::GetMsgFromErrorTable: INFORMATION: Error message is The provided database version is not supported. Please enter a supported database.
VMware: Srm::Installation::Database::CheckDbPopulatedAndNeedsUpgrade: ERROR: Unsupported database instance.

Caught red-handed, I was trying to “upgrade” an SRM 4.0.0 installation to 5.0, which is not supported. I didn’t need the current config as it was easy to reconfigure, so I dropped the tables and was able to continue on and finish the installation.
