I run MediaPortal on XP Pro. I just uninstalled everything (I had two MediaPortal entries in my Add/Remove Programs) and reinstalled MediaPortal 0.2.3.0. And when I tried to run it with my non-privileged user, it didn't display and crashed when I tried to close it (with Alt+F4). Then, I gave my user "Full Control" permissions on the MediaPortal directory and everything worked smoothly.
What do the permissions look like in your Vista MediaPortal installation directory? |
