Launcher V2 doesn't work on one pc

[PassJ]

I have this game installed on two PC's. both fresh installs as i've only bought it recently
On my laptop (intel i5 1060 6gb) it launches fine & runs impeccably.
on this 1st pc(Ryzen 2700x + Gtx 1080) the launcher just doesn't launch the game, i can however launch the game from the .exe file but i can't find the actual launcher to try admin mode or other troubleshooting.
both games are installed on C drive, both games give a 'mod pathing' error on opening the launcher.
I've reinstalled on this Pc twice, uninstalled the Pv2 launcher in windows .ect
nothing seems to work

1st did you get the Steam, Paradox or Gog version?

2nd installing to C probably makes this a antivirus settings error but without basic information your guess is as good as any

Steam version, should have specified sorry.
i read something about AV but i only use windows defender and there's rarely issues (since it launches fine on my laptop)

Please try this:

- exit the Steam app entirely
- uninstall Paradox Launcher v2 from the Windows "Apps and features" utility, if still present.

Delete the following folders if still present:

- C:/users/<UserName>/AppData/Local/Programs/Paradox Interactive/
- C:/users/<UserName>/AppData/Local/Paradox Interactive/
- C:/users/<UserName>/AppData/Roaming/Paradox Interactive/launcher-v2/
To see the AppData folder you'll need to enable View Hidden Items in File Explorer.

- run steam.exe as the Windows Admin user

- run the game from the PLAY button in Steam

IF that doesn't help, in this folder are some .log files:
C:/users/<UserName>/AppData/Local/Paradox Interactive/launcher-v2/
Please attach them here.
