Need to find old .msi

hi trying to find epicgameslauncherinstaller-2.6.0-2730263.msi so i can repair my launcher so i can uninstall it.
couse when i trying to install fortnight it says the folder path epic games contains an invalid character.

If it’s saying there is an invalid character that is likely due to a Cyrillic character (eastern European languages).

Try installing it to a different folder, an old version of the launcher will have the same issue installing (and there is no place you can download it anyways).
