so while i was deleting stuff from my computer for extra space I accidentally deleted hammer. I know it seemed stupid but at the time I didn't care about making maps.Now these days I want to make my own maps and i accidentally delete the EXE file. and another thing when i click on Hammer.bat it said "Windows cannot find 'C:\program files(x86)\steam\steamapps\common\team fortress 2\bin\hammer.exe.Make sure you typed the name correctly.
Maybe verify the game cache or reinstall the TF2 files? It should bring back anything that was deleted
I'm thinking verify game cache should work since it looks for all of the files. Though if it won't, then yeah you gotta reinstall TF2.
