At the TES Nexus it says:
3. Unzip the BOSS.zip to your ..\Oblivion\Data folder, so that BOSS.exe is in the same folder as your mods.
I found the Oblivion/Data file but when I attempt to unzip the files to it I get this error:
Extracting file: C:\Users\Joe\Downloads\BOSS_1-5_Stable-20516.7z
Extracting to "C:\Program Files (x86)\Bethesda Softworks\Oblivion\Data\"
Use Path: yes Overlay Files: no
Error: Access is denied
Extracting BOSS.bat Unable to create file
The only mod I've downloaded so far was OBMM, which does it's thing automatically. What am I doing wrong?
