Problem with Mac OS High Sierra and VMWare Fusion

[AAFS2000]

I installed on my Mac Book a VMWARE Fusion where I run Windows 7.  
I used the Mac OS El Captain and it was all working. But unfortunately, I installed Mac OS High Sierra and VM stopped working.  
To try to recover the data that was lost in the VM, I installed VMWARE 10 (trail version) but when I try to open the VM it displays the following message: "Cannot find a valid peer process to connect to".  
Can you help me? 
I need to retrieve a project that is saved in VM.

Open your Security & Privacy settings and unblock Fusion if it says it is blocked. Reboot your Mac if that doesn't help. This is a common complaint with Fusion and macOS.

Thanks, but that's not it.

If anyone knows how to recover data that is in the VM, I'm happy.

If I can not open the VM, no problem, I just need the data. I just need to recover a JAVA project that is Windows 7 installed on the VM.

I do not think I want to use the VM anymore. I can not trust a VM that stops working and loses my data. But I need to recover my project.

What you're describing is a common complaint in this combination. So have you actually tried to reboot your system first? This doesn't mean your VM is corrupt.

But I still can not access a project that is very important.

For me, I made a mistake when I used VMWare Fusion. With Boot Camp I would have no problems.

Now I need help to recover my JAVA project.

Something else you can try the others have found success in doing is to reinstall fusion and then see if you can boot.

Hi,

Actually "it IS it". The problem is that the system extensions blockage by gatekeeper in macOS 10.13 is a bit unpredictable in whether or not it is going to display the blocked system extension or not.

Please see:

For the currently known ways of trying to fix this.
