I am trying to patch from the CD to 2.15 on a new computer. I get a "some files you tried to patch are locked or missing patch not applied". Also there is no Mods folder in my dom2 folder. When I got to prefernces in game there is no where to install mods. So I decided the Mods foldier was the "missing folder" and reisntaleld and tried to apply the patch, it still is not working.
"Linux or Windows?" Try again! That's an error message from the Mac OS X patcher.
I had the same problem originally. Here's the fix:
Before running iPatch, it is necessary to Command-I on the installed dominions2 application and set it to read/write.
Regarding mods, you have to create the Mods folder manually within your personal "dominions2" folder in your home directory (*not* the dominions2 application bundle) and then put the mods there. Incidentally, mods are usually packaged in a folder. You need to put the *contents* of the mod's folder into your "mods" directory, not the mod's folder itself.
