so if you have an older program, you update to Windows 10 at YOUR risk of problems also, only CURRENT products will be tested and updated for compatibility with Windows 10 bottom line, old programs require a matching old operating system 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.
Microsoft changed their operating system and THAT is why your old program won't work, not because of anything Adobe did. Adobe did not change your old program to make it stop working. Owners of old programs simply have problems with Windows 10.
