Applications not scaling correctly on 4K displays

If you have applications that are not scaling correctly on your lovely 4K monitor this can be helped/resolved by using a windows manifest file for each application that you have the issue with. You need to make a single registry change and then create a applicationname.exe.manifest file in the folder than the application runs in.

The Registry entry is:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\SideBySide]

"PreferExternalManifest"=dword:00000001

The applicationname.exe.manifest file (eg payroll.exe.manifest for Sage Payroll), would contain the following code:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
