Hey, so I've compiled all of the maps and the launcher into one ZIP file for easier manual installation, since the auto installer didn't work for me, and it seems like it isn't working for others either, based on other posts in this thread, so I want to do something to help. With your permission, the compiled zip folder will be hosted on mega.nz and I will keep it up to date as new updates are released.
The error message in Powershell with the auto installer script flashes by so quickly that I had to record it with OBS and freeze-frame the video in order to even read what it said. Something about a lack of permissions is what I was able to gather from it. I'm probably doing something wrong here, but I could not get the policy bypass to work, and I didn't feel like doing the research to figure out what I'm supposed to do, which is why I devoted the time to manually downloading and installing everything, and then compiling it all into one zip folder so that the process would be easier for everyone else having the same problem with the automatic install script.
