You will either need an older computer or a different application. A company which only supports a .0 version of an OS usually means they aren't really supporting their customers. They are expecting you to run an application on an OS without any security updates or improvements. There are 7 years of CVE's in the kernel, libraries and other parts the customer has to live with if they want the application. Good luck. -- Stephen J Smoogen.

All those moments will be lost in time... like posts on BBS... time to reboot.
