To resolve these issues, try one or more of the following solutions.

Solution 1: Remove any in-progress installations

Disclaimer: This procedure involves editing the Windows registry. Adobe doesn't provide support for editing the registry, which contains critical system and application information.

  1. If the Inprogress key exists, delete it.
