paradox launcher v2 setup wizard ended prematurely

[DaiwaScarlet]

Hi, I got a new PC setup and when I tried to reinstall Vicky 3 on steam, I can't start the game because the paradox launcher v2 setup wizard would end prematurely. Windows shows an error window saying MSI309E.tmp is not a valid Win32 Application. I'm currently running on Win 11 Japanese version. Both the setup when starting the game on steam and the launcher I downloaded from Paradox website would fail to similar errors with different .tmp file names.
Any help would be extremely helpful, and I want to express my gratitude in advance.
I can also provide more info if needed.

Can you run the game from victoria3.exe directly from File Explorer okay?

Hey, thanks for the reply. I was able to run victoria3.exe directly yes. In fact, I solved my problem by starting from HOI4 and installing paradox launcher with it. I don't know how it worked but now I can open vic3 from steam directly.
