After a power outage on my Imac I receive this message when trying to open Windows 8 in Fusion. I attached my problem report with the details. I have researched the knowledge base but I don't find anything specific for this issue. I appreciate any support you can provide. Thank you! Michael
Reinstall VMFusion and then go to the Security and Privacy tab of the System Preferences. You'll see that VM Fusion is requesting access to part of your system which you need to authorise. Click the button and it should work.
