I recently upgraded from Vista to Windows 7 and can't get my PageMaker to install. I realize it's an obsolete program but I have my business cards and other inportant items in that program. I would not mind upgrading to something newer in Adobe as long as there is a way to transfer my most important projects. I do not have the time to recreate these documents.
You can upgrade to InDesign from PM for only $199. ID will open PM 6 and later files. They might not be perfect but with documents such as business cards, I don't foresee a big problem. You buy directly from Adobe from here:
Hope that helps,
