When I run Adobe Acrobat XI pro, it won't start. Nothing happens as if I did nothing. Even I uninstalled and installed again, it's the same. What's wrong?
Use the Acrobat Cleaner tool for uninstall. Install the last version.
The Adobe Reader and Acrobat Cleaner Tool removes a standalone installation of Reader or Acrobat, including any preferences and settings that may be preserved during a standard program uninstall. The tool has both a user interface as well as a command line interface.
