When I installed the window was stuck with the message "installing" for about an hour and I just closed it and found the 2 downloaded files and ran cakewalk.exe. It installed with the same windows and prompts we've always had. No reason to run instruments.exe if you've already installed the instruments with Platinum.
I used it today and for me it worked better than Plat as far as crashing. No crashes, very stable. Hopefully tomorrow will be the same.
