Virtual Machine Manager Configuration Analyzer (VMMCA) is a diagnostic tool that verifies configuration settings and minimum system requirements for your computer that are important to running Microsoft System Center Virtual Machine Manager (VMM). VMMCA scans your environment and reports common configuration issues and suggests best practices. You can run VMMCA before or after installing VMM.
This tool is freely available, but interestingly enough, it only operates with 64-bit Microsoft operating systems. However, VMMCA can be used to scan both 32-bit and 64-bit computers.
