My computer guy has no idea. The MS error code pointed to an unamed conflict so he deleted or updated everything he could - drivers etc - as well as other things. I'm not a computer guy so I can't be specific but I've known and trusted this guy for over 25 years so when he's tried everything he can think of and is still stumped I take him at his word.
While a clean install sounds like a good idea I'm concerned about replicating everything I have in my current PS install. Making a list and reinstalling Topaz, Luminar, DXO , NIK etc., is straightforward, but I have "assets" that I have assembled over time like custom brushes, overlays, library files (replacement skies etc) that I'm not sure where they are kept and how I would add them back again - I don't know what the original instructions were. I can't see how I would get back to where I was after a new and clean install.
I have an Asus PA 90, a relatively new, top of the line machine and I find it hard to beleive that there should be a conflict in such a product. I didn't assemble this thing myself and there are no "off brand" parts etc. If I'm having a problem then so should everyone else who bought this machine. It's from their Pro Art line, designed and built for creators so my software installs should be be common stuff and the hardware components should be compatible with Adobe products - that's what they're built for Frustrating.
