XC8 compiler installer hangs on installation

If you are having a problem with the MICROCHIP XC8 installer hanging on installation under Windows 10 — (see screenshot below):


Very easy solution…


Change your screen resolution to 1080p, and TURN OFF all “screen scaling/screen zooming” settings

Reboot your computer (trust me, just do this step)

The installer should work fine now.

when done, change your screen back to whatever settings you previously had it at…

let me know if this works for you.  I spent 2 hours trying to figure this one out.

    Thank you very much, it also solved my problem that is the same as yours, I think more and more people will meet the same problem at upgrading his PC.

    Hi all,

    This worked for me:
    1. Download the installer
    2. Right click on it and choose Properties/Compatibility and check “Override high DPI scaling behavior. Scaling performed by System (Enhanced)” and “Disable fullscreen optimizations”. Click Apply.
    3. Run the installer.

    No need to reboot the PC.

    Marins solution worked for me. (XPS15 4k + ext 4k monitor)
    If you see flashing text in the options page, you have a problem.
