And this is why software should always be offline and installed from media. My copy of Photoshop 6(CS1) doesn't care what I do with it, it's software that does a job. I've tried updated CS versions of Photoshop thanks to friends and other means, and frankly? CS1 does all of what I need or want, and very little of what I don't.
Working with software not installed and accessible on an airgapped offline machine is a bad idea.
