Verify Analysis Services cumulative update build version
Applies to: 
SQL Server Analysis Services 
Azure Analysis Services
Fabric/Power BI Premium
Beginning with SQL Server 2017, the Analysis Services build version number and SQL Server Database Engine build version number do not match. While both Analysis Services and the Database Engine use the same installer, the build systems each use are separate.
In some cases, it may be necessary to verify if a Cumulative Update (CU) build package has been applied and Analysis Services components have been updated. You can verify by comparing the build version numbers of Analysis Services component files installed on your computer with the build version numbers for a particular CU.
Verify component file version
To verify component file version,
- Go to SQL Server 2017 build versions.
- In SQL Server 2017 cumulative update (CU) builds, click the Knowledge Base Number for the build you want to verify.
- In the Cumulative Update (#) for SQL Server 2017 article, in the Cumulative Update package information section, expand Cumulative update package file information.
- In the SQL Server 2017 Analysis Services table, check the File version for the msmdsrv.exe component file. If the CU has been applied, the file version number should match the msmdsrv.exe file installed on your computer.
