Hello,
I hope I am not asking about something that has already been answered, but the only relevant posts are about 2-3 years old and mostly stating that the Updater can't find the directory for NWN EE, which from what I see now is not the case (though I do have to manually navigate there).
I have moved all relevant files as instructed in the Documents directory and the modules I've tried to patch are in the install directory. I run the PRCModuleUpdater (have tried running as Admin as well), it decompresses and begins to perform some actions, but it fails at various stages. I have NWN EE installed on 2 different PCs, on both it either fails on "Checking for overwrites"or it manages to proceed to find conflicts and once I continue it proceeds to "Setting module properties for ..." but just ends there without performing any changes. Overall I haven't been able to patch any module, (I initially tried a larger module, but now I'm only trying to get Contest of Champions patched before moving on).
I guess I should point out that I have a somewhat "hacky" installation (the NWN Documents directory is outside of the Documents folder but referred to by junctions), but the Toolset and the game work as they should and the updater lists both .hif files and all modules in the installation directory.
