I have been facing a problem I don't believe has been posted here before.
For context, I have been trying to install B&W for the past couple days. I had initially installed the game before I knew about this guide, and once I knew about it I uninstalled the game (via the search tool on file explorer, and later the control panel's "uninstall/change a program" tool, and finally using RevoUninstaller) and attempted to reinstall. When trying to reinstall the game, the automenu screen showed that the game was still installed. When I hit the uninstall button, it showed me an error saying, "An installation support file could not be installed. Catastrophic failure". After deleting all the registry keys the guide said to I could find ("HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Lionhead Studios Ltd\Black and White Clan Patch", "HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Lionhead Studios Ltd\Black and White Patch", and "HKEY_USERS\S-1-5-21-2309910519-2795697514-4011825439-1000\Software\Lionhead Studios Ltd\Black & White" were not found, however a different, yet similar looking key in the "HKEY_USERS" category was found, which I deleted), the installation seemed to be working smoothly.
My current problems: Whilst all the creature addons you recommended successfully installed, the Villager Banter addon (as well as the 1.1 and 1.2 patches) give me the same "catastrophic failure" error like before. I don't know what to do from here. I thought about deleting the registry keys containing "InstallShield", but I don't know much about the registry and, seeing as I don't know much about computers, I'd rather not take the chance without guidance first.
However, this isn't my main problem. Since the villager banter mod is simply an add-on, and the 1.42 patch still worked, I technically don't have a issue that stops me from playing the game. But, for whatever reason, after the Lionhead and EA logos pop up and the little preview/video (w/e it is) plays through, the game crashes about ~1-5 seconds after the first loading screen begins. No error is shown, the game just closes. I have tried running the game through runblack.exe and automenu.exe, and with the configuration of fullscreen and windowed mode, all with my native resolution of 1920x1080 with apps set to run as administrator and all users given full control over changing/modifying the app.
I have no idea what could be causing this problem, and I present these two errors in some off-chance that they may be connected or solved together. My apologies if either of these issues have been brought up/solved prior, I admit to have very lightly skimmed through the comments to see if anyone else could have these problems.
