Reading Environment variables problem

Hi,

I am using ReadVariable with the option VIX_GUEST_ENVIRONMENT_VARIABLE and I am getting blank values. I am logged in as the Administrator.

Note, the two environment variables I can retrieve with no problem are TEMP, and TEMP.

However, I can't retrieve variables like WINDIR, PATH, COMSPEC, and even SYSTEMDIR. I have tried to put the environment variables into section for this user in the advanced pane of my computer. Through the VIX inteface I only get blank values. I can retrieve them all on the command line within the VM with no problems

Is there a limitation of VIX?

Thanks,

Vinay
