Adobe did not change your old program to make it stop working. Owners of old programs simply have problems with Windows 10. says Encore, but sometimes required for ALL Adobe programs (this is NOT the same as using an Administrator account) or Run as Administrator to assign FULL Windows permissions may help. RIGHT click the program icon or EXE and select a compatibility mode in the pop up option window Two ideas that MAY work to install and/or run old programs in Windows 10 you obtained the special CS3 serial number AND you downloaded the special installer program?ĬS3 and Acrobat 8 activation server is retired see reply #1 So I searched as best I could on the help pages and found where it said to get a new serial number and download these files and reinstall. I tried via internet and it said no connection, I tried via phone and got a message saying that that is no longer available. I opened Photoshop and that is when it said that my Activation was broken or invalid and to reactivate. Shortly after the update ran I was using Acrobat and a box suddenly popped up telling me to open one of the other CS programs to continue using (basic gist - cannot remember the exact wording at this point). Acrobat somehow installed, but I am honestly not even sure how that happened since I said to run Setup but then never got the chance to pick what to install since it just disappeared after the box that says 'Initializing.' We are a small printing company, and I use Photoshop and Acrobat daily. Aside from that - this is the only other issue I am having, but it is a big one. This particular one did erase printing preferences for certain printers we use (running direct-to-plate and it reset all of the plate sizes for each printer to letter, so I had to go in and fix that). No reloading Windows, no reformatting or rebuilding happened. That is literally all I did - run an update like I have a million times before.

A Windows update ran when I logged into my computer Wednesday morning.
