With the latest update of CRM 2011 we have compatibility with SQL 2012 server. I have got a chance to install CRM application on top of SQL 2012. If you are successful in installing CRM then trying to configure Reporting Extensions for CRM you might encounter the following error:
"Installation of Microsoft Visual C++ Runtime failed. Exit code: 5100"
After we get this error it is our usual understanding that Visual C++ Runtime is failed to install. If you can already see the Visual C++ runtime in the programs and features of your computer then that is the one which is installed by SQL server 2012. If your CRM setup which is running is an old one it doesn't support the latest version of C++ runtime.
To avoid this you can go download the latest CRM setup from the following location:
After downloading the file and extracting everything you will be able to see a folder named: "SrsDataConnector". This will help you in installing and configuring Reporting Extensions for CRM 2011 with SQL 2012.
Hope this helps!!!
Enjoy reporting with Dynamics CRM with SQL 2012.
