I looked up in http://helpx.adobe.com/creative-suite/kb/acrobat-failed-launch-30-days .html for a solution in WHY my acrobat X pro is not lauching anymore and found this procedure: but this applies to a newly installed CS6 just after 30 days but I have now CS6 (and acrobat X included) working for months and again acrobat does not start, this is not the first time I reported the problem and again I have to deactivate/activate the entire CS6. This is NOT A SATISFYING SOLUTION
Solution Reactivate Acrobat through another Suite product:
Important: It's necessary to perform the following instructions when connected to the Internet. Select a following product when requested to launch a CS6 Suite product: Photoshop, After Effects, Adobe Premiere Pro, InDesign, Flash Professional, Illustrator, and Dreamweaver.
- Launch a CS6 Suite product.
- Choose Help > Deactivate.
- Follow the onscreen prompts to deactivate.
- Close the application.
- Launch a CS6 Suite product again.
- Click Accept to continue launching the product.
- Sign in with your Adobe ID associated with CS6 suite.
- Close the application and relaunch.
- When prompted, click Sign in.
- Enter your CS6 Suite serial number and click Next.
- Close the application and relaunch.
To permanently resolve this issue, update all of your CS6 applications via the Adobe Application Manager.
