I just read quickly the license agreement for installing Registry Mechanic, and here is something I read that contradicts with what you are reporting here:
"If you are downloading a free trial version of the Software, you may use it on one or more computers for an unlimited period of time. However, you are not entitled to receive technical support nor the full functionality that comes with the Software until a licence fee has been paid."

Anyway, this does not resolve your problem. You may want to address this to these companies' tech support or you can manually remove them if you are very comfortable to delete things from the registry.
