Hey, I’ve got the exact same problem, and I still can’t do anything.
Can’t install, can’t uninstall, can’t launch.
I ended up deleting absolutely everything related to brave (AppData/Local/Bravexxx, Program Filex (x86)/Bravexxx), but I still have the same error.
I saw somewhere online that the error code might be due to Microsoft Visual C++, so i uninstalled/re-installed it as well, but no luck.
At some point, with an old Brave Standalone installer for 32 bit (I’m on 64 bits) I managed to reach the installing phase, but then an error message told me that I already had a more recent version of Brave installed (which I dont anymore, but seeing as I brute-deleted everything instead of doing it properly, because I kept getting the error cpde, that might be my fault).
Anyway, if someone finds a solution, that’d be great.
Thanks everyone !
