Illustrator 7.0

I wonder if you could partition the new PC's HD and install Windows XP ( or whatever version you were running on the previous PC ) on one of the additional partitions?  What happened that you had to replace the previous computer ( just curious )?  A 64bit version will run on Windows 10 because it is a 64bit OS.  But, if you are able to install on a partition the previous OS, then you may be able to install Illustrator 7 onto that OS.

Sorry but no modern computer will be able to run Illustrator 7. In order to get a version of Illustrator that will work on your computer you will need to get a subscription to either Illustrator CC 2021 alone or to the whole of Creative Cloud.

The 64 bit upgrade is called Illustrator 2021, which is the current version.

@Sal5EFB I don't know if you are going to get 7.0 working on a new Windows 10 platform. That version was first released in 1997. So... 24 years ago? Here's how to get the lastest version: Industry-leading vector graphics software | Adobe Illustrator
