Acrobat DC. What Adobe claims is the latest version.
Windows 7 on Acer laptop.
I tried this, and these other "fixes".
Reloaded Acrobat 4 times
Menu item help->repair
Turned off Edit->Security(special)->Load in Protected Mode
Norton Power Eraser
Still locks up.
If I reboot, for 10 minutes, I can use Acrobat DC, then, I get (Not Responding) and have to kill it using Task Manager. Sometimes get a message "Failed to connect to a DDE Server."
Is Acrobat "free", now "crippleware", to encourage users to buy the commercial version? Are you ending Acrobat "free"?
