Windows 7 does have a Compatibility Wizard but if you have tried that and the games still will not install or play correctly then there is little you can do. Especially so with Win 95/98 games where Win 95 is now some 17 years old.
That said, you 'may' be able to get some of the games to work, depending which version Windows 7 you have. If it is Win 7 Professional or Ultimate Microsoft offer a free download of "XP Mode" from;
Install that within Windows 7 and it offers you the opportunity to install XP compatible games within this XP Mode and run them.
Even so, not all games will install or run, because of their age.
I hope that helps.
I recently installed a Windows 95, among other Windows 98 and XP games on my Windows 7 operating system and it keeps saying there are incompatibility issues. Is there anyway I can make them compatible? I never want to let these games go and would like to continue using them
