The installation of Oblivion went just fine, but whenever I try to install the patch (North American v1.2.0416), the patcher stays at 0% and shows up in Task Manager as "Not Responding" after about 30 seconds. I don't have Shivering Isles and am not using a no-cd patch; I've literally just installed Oblivion and not touched it since, aside from running it once in case it needed to run diagnostics for the patch to work. I have tried reinstalling Oblivion, redownloading the patch, and running the patch from a clean boot and as the system administrator with no change.
Help would be greatly appreciated. If you don't know of anything that would help to get the installer to work, is there another method for installing the patch (e.g., another type of installer that can be used, or would copying files and doing some manual editing be a possibility?)?
Edit: I just tried installing an earlier patch (1.1.511) and it didn't work either, so it appears to be a problem with the installer and not the patch itself - which seemed like the obvious option, but thought I'd get confirmation nonetheless. Is there any third-party program that is necessary for RTPatch to work? Could my something like my firewall be preventing it from working? (I doubt its the firewall itself; I've had no popup, and the firewall was off when I tried running the patch from a clean boot.)
