I have CS6 running on Win7x64 and when I try to launch it, it gets as far as the Color Efex 4 plugin and just sits there 3-5min then loads.
Tried it with botyh 64bit and 32bit Photoshop. When I remove the plugin, Photoshop loads in maybe 5 seconds.
Lightroom 4 loads just fine, and Color Efex on its own loads fine, just seems to be with Photoshop loading the plugin during the splash screen.
I just formatted my computer a few days ago, so figured no biggie, maybe something installed improperly so formatted the system again and reinstalled everything... and same issue.
I have tried numerous uninstall/reinstalls, used the CS5/CS6 cleaner tool, tried installing CS6 then updating before adding in Color Efex, tried installing and running without any updates and same issue.
Tried the solutions found at https://support.google.com/nikcollection/answer/3004716?hl=en&ref_topi c=3002203 as well.
Not sure if a Color Efex issue with Photoshop? or a Photoshop issue with Color Efex, so, thought I'd post here and see if anyone else had this problem and maybe found a solution.
Thanks
