I was able to unzip it with 7zip, but then when I tried to launch the VMX it just says:
Unable to open configuration file "C:\Documents and Settings\user\My Documents\haiku-19664\Haiku.vmx":
(null)
Yes all of that including the "null" is the alert box error message, please repackage this VM and make sure it works!. I look forward to the new image.
