u mean rename my C:\Program Files\Silkroad or rename the things inside the C:\Program Files\Silkroad such as sro_client, silkerrsender, and the rest of the game files...
I think it's just the folder you install it to. Not sure though, I only have one version but it makes sense because if the file names are the same in the same place it'll overwrite.
aight i think i know wat to do just change the folder of Tsro.. btw i wonder if my account in troy is still ok i rememeber it got hacked haha havent checked it for a long time...
Rename the folder you have tSRO in as "tSRO". When installing iSRO name the folder (when it asks you where you want to install it) iSRO. Do the same with any other version you want to install.
