CRM Update Rollups - Which Files Should I Apply?

Microsoft has settled on an every-other-month release schedule for CRM Update Rollups.  The update rollups are released as a set of files meant for updating different CRM components.  Here are some guidelines to help you understand what each available file is meant for and whether or not you will need to apply it to your CRM system.  This post is specific to CRM On-Premise only!

1. The first thing to understand is the file naming convention.  The files are currently named as follows:
   
   (CRM Major Version) - (Knowledge Base Article) - (Hardware Platform) - (CRM Component) - (Language ID).exe
   
   So an example filename such as this: CRMv4.0-KB979347-i386-Server-ENU.exe tells us that this file is meant for application to a CRM 4.0 Server running on a 32-bit platform in the English (US) language.  In addition, it lets us know that KB979347 is the knowledgebase article that provides the details for this Update Rollup file.



2. The possible platform values are i386 or amd64.  If your hardware is 32-bit you will want the i386 files.  If your hardware is 64-bit you will want the amd64 files.



3. The possible CRM Component values are:

Client - The CRM Outlook Client
DMClient - The CRM Data Migration Manager (also known as the Data Migration Wizard)
MUI - The Multi Lingual User Interface Pack
Router - The CRM Email Router
Server - The CRM Server
SRS - The SQL Server Reporting Service Connector for CRM


4. The final thing to understand is which of the above components you need for your specific environment.  Well everyone (running an on-premise system) requires the server file.  If you have CRM Outlook clients you will need to apply the Client update to your CRM Outlook Client machines.  Most organizations do not require the CRM Data Migration Manager Rollup file unless they are using that tool to migrate data into CRM.  If your system is not multinlingual you obviously do not need the Multi Lingual User Interface Pack Rollup file.  If your system CRM email is handled by the CRM Email Router then the Router file must be applied to the machine running the CRM Email Router.  Finally, if you have an IFD (Internet Facing Deployment), you will need to apply the SRS file to the machine running the SSRS Connector for CRM so that your users can view reports over the web.  If your system is not exposed to the internet, you will not need to apply the SRS file.
