1. Ensure that a supported version of Adobe Acrobat or Reader is installed. If both Adobe Acrobat and Reader are installed, ensure that both are supported versions. Look for the latest “Creo View Clients and Toolkit Software Matrices” at Reference Documents for detailed version information.

2. If a supported version of Adobe Acrobat or Reader is already installed, check that the Windows Registry software InstallPath values for Adobe Acrobat or Reader, located under the HKEY_LOCAL_MACHINE key, point to valid installation directories.

3. If the Windows Registry is correct, uninstall and reinstall Adobe Acrobat or Reader (or both, if both are installed), and then uninstall and reinstall Creo View.
