[2023] No read/write access

Has the launcher ever worked on this machine? Or never yet?


What antivirus app do you use? You need to make sure all these apps are in its exceptions lists:

eu4.exe and dowser.exe (in the Steam EU4 folder)
C:/users//AppData/Local/Programs/Paradox Interactive/launcher-v2.2022.15-rc/paradox launcher.exe
C:/users//AppData/Local/Programs/Paradox Interactive/bootstrapper-v2.exe


IF that doesn't help: Right click on Documents in the left column of File Explorer, just under This PC there. Go to properties, location. What does it say in there?  

Well, the launcher is having trouble getting to that folder for some reason - it does exist I assume?

In the Windows search box enter Ransomware. Enable Controlled Folder Access if disabled, then go into the Apps Allowed through list, and add all those .exe files I listed there. Also make sure eu4.exe is NOT set to run as the WIndows Admin user.
