I have Photoshop CS4 Extended. This is an older program but has worked fine for years. It has served all my basic needs until recently. During the past couple weeks it has started freezing up, screen goes black and flashes and won't respond. I've tried running as Admin and other users. It says there are no updates needed... Any help is greatly appreciated!!!
As far as I know, CS4 is not 64bit... 64bit programs did not start until CS5
Anyway...
Owners of old programs simply have problems with Windows 10... none of which is Adobe's fault... Adobe did not change your old program to make it stop working... Microsoft changed their operating system and THAT is why your old program won't work, not because of anything Adobe did... Also... every time Microsoft issues a Win10 update, there is the risk that an old program that HAS been working after the initial Win10 upgrade will STOP working... bottom line, old programs require a matching old operating system
An idea that MAY work to install and/or run old programs in Windows 10... works for some, not for others
-RIGHT click the program icon or EXE and select a compatibility mode in the pop up option window
-or Run as Administrator http://forums.adobe.com/thread/969395 to assign FULL Windows permissions may help... says Encore, but sometimes required for ALL Adobe programs (this is NOT the same as using an Administrator account)
-or more on permissions https://forums.adobe.com/thread/2293598
NOTE - Win10 anniversary update version 1607 has caused MAJOR problems with old programs, so the above may not work
