HEEELLLP !!! Server startup error !!!

I'm trying to set up a pure Dayw Overwatch server, I made the paço a paço, more when I started the server of this error >>> "Windows can not find '.\Expansion\beta\arma2oaserver.exe'. Make sure that the name was entered correctly and try again. "

Did you install arma2 an arma2oa into the same folder? In the bat file use the arma2oaserver.exe in the root folder. Do not use the expansion folder.

yes it was all right, I followed a tutorial that taught me to create an overwatch server, but it was very old, with the current files I could not make it work, I started to start the server but my game did not open: /

Is it working or no? If you want I can setup the server for you. Send me a message if so
