[Affiny Photo - Paint Bush Bug With wacom tablet/mouse Windows]

Heya, 

I have run into an annoying issue when using the paint brush in affinity photo with a Wacom tablet on windows 10. 
Attached is a gif of the issue, but to describe it, each time I try to paint some areas I cover with my bush don't get any colour added, and then i get some weird graphics glitches where areas I have painted are removed. 

Im using the latest version of Windows 10 and affinity photo.

[Installer starts a process and then closes, Windows 10]

Hey all, 

I'm unable to run any affinity installer to either update my programs or install them from scratch. Every time I try it starts a new process and then immediately terminates it, I have tried running it in compatibility mode, as Administrator and even redownloaded the same files. It's only happening with affinity products, I have been able to install other apps just fine on my machine.
