CUE exits immediately

Hi guys, as far as I'm aware nothing has changed recently on my system however CUE now fails to start - or rather it starts, shows system tray icon and then exits after about 10 seconds. The GUI never appears. I found the log file:

Ends after that last same line every time. Things I have already tried:

 

Updating to latest version of CUE.

Uninstall, remove all settings, reinstall.

Repair installation.

Reboot many times.

Update ASMedia USB drivers from ASUS (Z170 Pro Gaming mobo).

Closing all other applications before running CUE.

Running CUE as admin.

Pausing Kaspersky protection.

 

Please help, I can't use my Scimitar!

OK I have solved my own problem. The issue seemed to be having a custom scaling factor set in windows display properties - I think I had it set to a non-standard value like 110%. I hope this helps someone in future.

Are you running a multi monitor setup?

 

If so, there are known problems with CUE and multi-monitor setups. e.g. the DPI issue.

Thank you so much Bane2087, you have given me the answer to my problem from this thread.:D: I can now open CUE2 with no crash.

 

I don't know if this fix will work for the others who were having the qt5gui.dll error but at least for me this has really helped, so thank you for posting what fixed your problem.

After 2 hours testing and endless search, this solution works for me, Thank You.
