[TECHNICAL ISSUE] Arc Launcher not compatible with x64 OS.

Translation: "16-bit application not supported. The program or feature cannot be initiated or run because it is not compatible with 64-bit versions of Windows. Check with the software manufacturer to see if there is a version available that is compatible with 64-bit Windows."

I have installed the Arc Launcher some weeks ago and I could open it and play with normality. But some days ago I tried to open the launcher and this message would pop up. It is strange because I was able to play just fine previously. I did not change my operating system nor I changed my discs.

Has anyone had the same problem as me? Does anyone know how to solve it or how to be able to play again?

◼️EDIT◼️▫️: I have solved the problem by doing a clean installation. Uninstall the launcher, run a cleaning application (like CCleaner) to fix any left registry issues, go to the installation folder and delete any folder left, reboot your PC, and install ARC again. It should be running again.
