Got purchased the game. Was hoping to get the installation started. But when trying to install the “INovaeInstaller.exe” from the download link provided I get a “Failed to write temporary UI Executable” and the installation fails.
I have attempted to run as admin, change the installation location and tried installing to only current user vs everyone and still no luck.
You are not alone buddy I got the game to install but when the new update started the install failed and now I am getting the same error as you but patience is a virtue and the devs are working on it. You should connect to the discord server where the devs are very active and can help there. https://discord.gg/WKNpu2
