I am having the same issue. However, the error occurs during installation of cncnet. I have uninstalled both cncnet and ra2 and re-installed multiple times resulting in the same error during reinstall of cnc net. Have tried reinstalling on different drives and cleaned out temp files with no success. below is the clientlog.
