Wasn't able to find this issue here or by googling but, after playing with the Quintessential Mod i wanted to give KM and DS9FX ago so installed another copy of BC fine, When i went to install patch 1.1 i kept getting a message saying that it had detected that they game was already patched and would close.
After deciding to uninstall BC completely and reinstall it to later patch and copy the BC folder over to use one for the QE mod and the other for KM the 1.1 patch still comes up saying that the game is already patched.
I have checked everything, made sure i deleted the BC folder but so far no luck.
