as Windows 3.1 is a retail app, and copyright is still held by Microsoft, you will need to purchase a copy. check ebay.com, or go to a local computer show, i have seen them there for a couple dollars.
OldVersion.com is not a place to share retail apps. Your post has been asked many times before. Had you searched the forum before posting you would have learned this already.
