A: ioGAS version 4.5 is Windows 7 certified, which means the software has passed Microsoft designed tests for compatibility and reliability with Windows 7.

 In version 4.4 and older, the program is not Windows 7 Certified however it will run and there are no known incompatibility issues apart from in v4.1 where users will find that there are invisible buttons in the File>Open and File>Export dialogs. It is still possible to use these buttons they are just not visible.
