Photoshop 7

No error code. Just what small box with text what I've quoted.

Looks to be pretty common error with multiple causes. Could not complete your request because of program error - Google Search

My guess is: since Photoshop old (ver. 7) the issue of compatibility with windows 10.

I have always had good success with another software, using the newest now Corel Paintshop Pro X8

Try saving your edited file to a different location such as your desktop and see if it works. Also you may try saving in a different format to see if it makes any difference.

Changing location and different format does not work, still given error

Frustrating I'm sure. One thing I have done with a different software that wouldn't run properly from the program files folder on Win8 was to completely uninstall with revo then install to the root of the c drive (or another partition) The software then worked fine.

I followed your advice and still does save.
Thank you for tip.

On my previous reply to you I should say: does NOT save. (sorry for my English)

I'm out of ideas. Wonder what's different in our setups that it works on my system and not yours.
