Cannot find default printer - FM10 Win7

I am using FM10 in Windows 8 (I occasionally get this error whenever adobe products are updated on my machine)

If you work in a more controlled environment (Federal Subcontractor with administrative controls everywhere), I contact my IT department , or if you have the administrator rights, perform the following steps:

1. Launch command prompt as administrator.
2. Type “appwiz.cpl” press enter
3. Right mouse click on Adobe Acrobat Pro and select change
4. Select repair and click next.
5. If necessary enter administrative credentials when requested.
6. Reboot workstation

I've seen that same error a couple of times when loading FrameMaker. As

I recall, a reboot fixed the glitch.

The Adobe PDF virtual printer instance should be your default printer within FM (use the free SetPrint plug-in to make this happen). That way you can keep your "real" printers as the default outside of FM. Is your instance of Acrobat Distiller working correctly? I would suspect that it's not - that may be why FM is complaining.
