Windows 10 is telling me it's incompatible with my AG Print Premium CD. Now, what should I do?
There are two ways to deal with this issue:
Apply a compatibility tweak to the main installer. Right click setup and then go to Properties > Compatibility. Choose a version of Windows that you know it works. Tick the Run as Administrator box as well.
Install a virtualization product like Virtualbox and emulate a version of Windows that you know AGP will work on.
Note: The computer where you virtualize another OS needs to support virtualization feature. You can check if it supports in the motherboard manual or in the BIOS.
