CS6 installed but (only) acrobat won't open

[unita]

CS6 fully installed on laptop - fully licensed, registered, activated etc.

everything works fine for a while but for no reason Acrobat stops opening.

no error message - just won't open.

we've already un- and re- installed the whole suite twice, but same problem occurs.

if I have mis-posted this, would appreciate if someone can tell me where I should be posting this.

cheers,

stephen

Two ideas that MAY work to install and/or run old programs in Windows 10
-RIGHT click the program icon or EXE and select a compatibility mode in the pop up option window
-and/or select Run as Administrator to assign FULL Windows permissions
