I have been getting this error for some time.
VMware Workstation unrecoverable error: (mks)
Exception 0xc000005 (access violation) has occurred.
My host OS is Windows Server 2008 R2 x64 and the VM is running Windows 7 Business x64. The machine is an HP Z600 Workstation. The error seems to occur when I try to access a file on the host OS from the VM. The file is shared using standard Windows sharing. trying to access shared files and folders on the host or other network locations didn’t seem to trigger this error always. I am not even sure if this was the cause.
After researching for a while I found this unrelated issue at the forums. Based on that I disabled acceleration for binary translation on the Windows 7 Business VM. So far it hasn’t crashed after that.
Note: This error started occurring after installing Windows 7 SP1. It worked fine without disabling this setting before SP1.
I haven’t disabled acceleration for binary translation on Windows XP 32 bit SP3 and it works fine.
I also have a Windows Server 2008 R2 x64 with SP1 installed. But I have allocated only 1 CPU to that VM and also it doesn’t access any files on shares. I don’t log on to that VM regularly. It just runs a SQL Server 2008 R2 instance.
Update July 12, 2011: I did not see this error for a while. Today I switched to full screen mode from my usual quick switch mode and immediately I got the error. Instead of disabling binary translation I had just one core specified for the VM. I increased the cores to 2 now and do not have binary translation disabled for now.
On Windows 7, if I check and uncheck turn on clear type, I see an immediate difference in how Outlook display the fonts. When I go to Visual Studio 2010, I don’t see a difference. This makes me think that Visual Studio 2010 is doing something differently from Outlook 2010 with regard to clear type.
Just to make sure that it is not the font that is causing this, I used Segoe UI in Visual Studio 2010.
