    Hi.

    I have a test server (used for different things) where we had CRM 2011 RU16 already installed and running.

    We had to uninstall CRM from this server, and now I'm trying to reinstall it.

    Install is failing because of we already have all the prerequisites installed, BUT an higher version of what the CRM installer is able to recognize. Therefore it tries to install the a bit, that fails because an higher version exist...

    Is there a command or a registry key I can change to make the CRM 2011 install WITHOUT the prerequisites checks?

    Many thanks for your help...

    The prerequisite checks are there for a very good reason, you should not want to disable this.

    The check you're facing is telling you valuable information. Basically there are some leftovers that need to be removed. Most likely you'll find some artifacts in either of these locations:

    - C:\program files\Microsoft Dynamics CRM

    - SQL Server databases: MSCRM_CONFIG and/or [OrgName]_MSCRM

    - Register: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSCRM

    If any of these locations exist, then you can remove these. That should solve the cause of the prerequisite check.

    Good luck,

    Hi.

    Thanks for answers. I have resolved myself by replacing the vcredist_x64.exe file coming from the installation package with the newest Visual C++ SP1 from MS download center.


    PS: yes I checked all registry entries for CRM, and they were cleaned. And CRM 2011 installation is a bloody b.... process....
