Ok so i was enjoying 3.0 then i installed 3.3 into my medviel total war program files.The result was an empty launcher box then a microsoft error report saying it encouterd a error along with a Avg alert.I expected this then installed the Hot Fix into the same program file,The result was the same error reporting and empty box in both my 3.0 and 3.3 start up box . Can some please explane what i did wrong in very laymans terms.Sorry bout all this love the mod though

Though, it's all included in the FAQ (besides in the release thread itself):
The target directory for all exe-setups is your MIITW directory, unless the installer or given instructions would tell you something else.
