I followed all of the steps like unzip it browse local files replace the "Granny_Data" but it doesnt work. Any tips on how to make it work?

How does it not work? Is there an error message and have you brought the game from Steam? And is this for the v1.3.1 mod?

like I replaced the "Granny_Data" and it didn't let me open granny so I tried doing the v1.3.1 mod (I was using the v2 at the time) and I have had experience with viruses and I put the v3 in a virus detector and 4 files was flagged as trojan and yes I bought it from steam.

When i replaced the file and tried to open granny it said something like "game files missing" or something like that

I just tried the v1.3.1 but it still didn't work
