Adobe will not do anything for you Photoshop 6 has no support. You will be much better off if you buy Photoshop elements. Its less then $100 and better than Photoshop 6 could ever be on windows 10. CS2 is not the usable on Window 10 and CS3 is not much better. Old software does not run will on Windows 10. Photoshop 6 is 20 years old. How may product do you own that are 20 year old and servicable. I e a 1990 300 ZX.
I too use (or used) PS 6.0 and it worked fine on Windows 10 until the latest update. Now I get the "error" message and it won't load. For the work that I do it did the job fine and it's quite frustrating having to buy new software. BTW I drive a 1999 Toyota van with over 260,000 miles every day... thank goodness Toyota doesn't send out self destruct codes so I'll have to buy a new one.
