Windows 10 and Pagemaker?
PM is unreliable on anything later than Windows XP. Most people can’t even install it on Windows 7. You’d be far better off saying good bye to that relic of the 20th century and move to something modern such as Serif Page Plus or scribus.
InDesign would be the best choice but is available by subscription only.
revthere any programs that convert PM7
Indesign CS6 will convert pagemaker documents with varying degrees of success. It is available as part of the Creative Cloud, under install previous versions.
