This error may occur due to the following:
- If the previous TMSM version cannot remove the SQL server information during the upgrade successfully
- If the previous TMSM version installation was corrupted. For example, the SQL database password cannot be decrypted successfully.
To resolve this issue:
- Download and extract the TMSM_Uninstall_Tool.zip file to completely remove the TMSM server.
- Right-click the remove TMSM.bat file and select Run as Administrator.
- Install the TMSM server. You should now be able to successfully install the server.
