Our software is compatible with any Windows version (XP or higher).  Perhaps there is a "user permission issue" with the installer (which is a 3rd party tool we purchased called InstallAware).  If possible could you let me know what type of problem are you running into. 

Note:  Please make sure to install the software into a folder which has read/write access, and the default installation location is: 
C:\Numerical Innovations\FAB3000v7 
or
C:\Numerical Innovations\ACE3000v7 
or
C:\Numerical Innovations\EasyGerbv5

Note: The folder "C:\Program Files" does not because it won't allow write permission.
