When you run the Microsoft Dynamics CRM 2011 setup file, there is a possibility you will get below error message: “Installation of one or more missing prerequisite components failed. For additional details see logfile C:\Users\[username]\AppData\Roaming\Microsoft\MSCRM\Logs\crm50svrsetup.log“.
If you open the log file, you will see this error message: “Installation of Microsoft Visual C++ Runtime failed. Exit code: 5100. Result: Asia“. The reason why this error occurs is the version of Microsoft Visual C++ 2010 Redistributable installed on your machine has the newer version number than the one included in the Microsoft Dynamics CRM 2011 setup package (It is 10.0.40219 on my machine). This might happen when you have later version of Microsoft products installed such as: Microsoft SQL Server 2012, etc.
The solution is to uninstall the Microsoft Visual C++ 2010 Redistributable both 32-bit and 64-bit version through Control Panel >> Program and Feature and then re-run the Microsoft Dynamics CRM 2011 setup file.
