Cannot Install VirtualCenter Server with MSDE as Database (2153)
If the MSDE_VC is already installed and the database has been created under it, the older database is not removed or overwritten.
To work around this problem, remove the MSDE_VC database:
- Choose Start > Settings > Control Panel > Add/Remove Programs.
- Select Microsoft SQL Server Desktop Engine (MSDE_VC).
- Click Remove.
If you are not able to remove the MSDE_VC database instance successfully using Add/Remove Programs, delete the VCDB.mdf and VCDB.ldf files under MSDE Install Folder\MSSQL$MSDE_VC\Data\.
