Thank you Bleek. Your suggestion did the trick on my home system. Now, I still have to troubleshoot my "locked down" system here at work. Even though the machine shows that I have admin rights, I know that is not fully the case. I will try reinstalling Apache and MySQL as services on the machine, shut down the services, and then retry running from the USB, so as to recreate the working setup prior to uninstallation of services. UPDATE: Not sure exactly why this makes a difference, but after reinstalling Apache as a service on the base PC, additional issues seem to have been resolved. I shut down the Apache instance on the PC, start the Uniserver on the USB and all functions are not working. Thanks all!
