Then I manually try to "C:\Program Files\Microsoft SQL Server\msas11. Mssqlserver\olap\data\tfs_analysis.0.db "Rename to" C:\Program Files\Microsoft SQL Server\msas11. mssqlserver\olap\data\tfs_analysis.0--. DB "

Then manually restart the service MSSQLServerOLAPService again, the error log appears again, and after viewing is unable to access the encryption key "C:\Program Files\Microsoft SQL Server\msas11. Mssqlserver\olap\data\tfs_analysis.0.db\0.cryptkey.bin "

Then I manually created the empty directory "C:\Program Files\Microsoft SQL Server\msas11. Mssqlserver\olap\data\tfs_analysis.0.db "and copy" 0.cryptkey.bin "from the directory you just renamed to the new directory
