I uninstalled rtw and deleted RTW folder. Used regcleaners to remove all trace about activion and rome total war.

When i try to install fresh RTW i get this messege

Error 1316. A network error occurred while attempting to read from the file
c:\windows\installer\rome - total war(TM).msi

I didnt find any installer folder from c:\windows even if i set invisible folders to visible..

Any one got any clue how i can install rtw without formatting c:
