[Dx4win] DX4WIN 7.07.02 with MMTTY 1.66G Win 32 Error Code 87

[Jim Reisert AD1C]

Hi Bill,

You should have mentioned UP FRONT that you're running Windows 7.  It 
took me a while to see this in your message.  I don't think Paul has 
Win7, nor will he probably support it until it's released in October.

There is a way to run Windows XP virtually inside Win7, assuming you 
have the correct processor.  See:

I did install this environment at one time, to test DOS applications 
running under Win7, but never tried the combination you describe.
