I can confirm the new version does not run anymore AT ALL on my W2k12 R2 Server, even after a fresh install. Same thing happens on my Windows 7 SP1 64-bit.
The message I get is: "Oops, something has gone wrong, please try again". That's it, no matter how often I retry, I always get this same message.
Adobe confirmed the problem with crashing explorer.exe is not yet solved, there should be another new version coming out this or next week to fix that. I hope it will also fix the new problem I just discovered.
It's a delight to work with this product. Love it!
