Common commercial plug-ins (e.g. Shine-off, Portrait Professional) will not automatically install into this Windows version of Photoshop.
Nik filters will install manually, the installer does not recognize this version of PS, but the program crashes shortly after launch if the plug-ins are installed.
No plug-ins, program runs.
I also have PS CC 2014 installed in OSX Maverick and the Mac plugins, specifically Nik filters, will install and work.
I do not see any entries for PS CC 2014 in the Program files/x86 directory as there are for every other windows version of PS suggesting a programming change.
I hope this is simply more buggy Adobe programming and not a deliberate attempt to sabotage Windows users and the plug-in market. If PS CC 2014 for Windows is not compatible with existing plug-ins its kind of useless/worthless if your workflow includes those plugins.
