I think I've figured it out. It had to do with permissions on the Coldfusion Builder folder in Program Files. Coldfusion Builder would run as administrator, but not as a User. I had to allow write permissions on that directory. I don't know if this is an eclipse thing or a Coldfusion Builder thing, but in windows a program should not require write permissions on it's install folder in order to run. If it needs to write something, it should do it under the users profile. I would consider this a bug.
