Installing older versions on Windows 7

[svetlik]

Have tried installing several older versions like the "yeti" which installs but won't run. Error says need to be administrator but "run as administrator" doesn't work either. there is no administrator on my PC just me. I once had this same version running on it for years but now can only install/run Master 99.

any help would be greatly appreciated.

Hi Edward,

 

A security update to Widows 7 makes the CD copy-protection process no longer work on Windows 7.

 

There are two possible work-arounds which you can read in post #26 in this thread.
