Is Diagnostic for DOS (CD) compatible with Windows 7?

The description of Data Lifeguard Diagnostic for Windows specifies that it supports Windows 7. Data Lifeguard Diagnostic for DOS (CD) does not mention Windows 7. Is the DOS (CD) version compatible with Windows 7 in spite of not mentioning that operating system in the description?

Because the DOS version bootable, it does not need to be compatible with Windows 7, the application will start before Windows 7 startup.

Thanks very much, oxter.
