I have Fusion 7.1.2 on an iMac that's running OSX Yosemite 10.10.3 with all updates Apple's software update utility offers installed. Running Windows 8.1 in a Fusion VM. Recently - possibly coinciding with Fusion update from 7.1.0 to 7.1.2 but user isn't entirely sure - when the Mac is put to sleep overnight and woken up in the morning switching across to the Windows environment (second desktop - two finger swipe sideways) shows the Windows VM shut down, with the Fusion "play" (start-up) arrow in the middle of the screen. Clicking that results in the "Cannot find a valid peer process to connect to" error. That persists if I quite Fusion and restart it - a reboot of OSX is the only way (we've found) to get the VM running again.
I can find lots of references to this error - in multiple VMware products and dating back years - but none that seem to describe this situation. Any ideas? I've already tried a reinstall of Fusion.
What's curious is that we have two near-identical iMacs with identical software versions right next to each other, and only one of them shows this problem. I can't find any settings differences between the VMs. More curious is the fact the Windows VM seems to be suspended, though we only selected "sleep" on the Mac.
Hope somebody has seen this and found a solution? Thanks!
