What are the contents of config.yml that is inside DevKit directory?

If you're seeing this happening, you might have something that is
interfering in your system.

Dunno why you have that as COMSPEC, but Console.exe is not a valid
command processor and could explain the reason why gem installation is
failing.
Please change your environment variables in your system settings and try again.

Luis,
Thanks for the prompt response. I noticed the comspec mix up right after posting this msg so tried to change it to the correct settings and everything is working once again. I thought to try it from a series of troubleshooting steps you were going through with someone else with a similar issue. Thx for your help.
