This Program Is Blocked by Group Policy

Group policy is a network administrator’s tool for deploying user, security, and networking policies to an entire network of computers at the individual machine level. The “This software is blocked by group policy” issue is almost always caused by the affected user allowing the Software Restriction Policy and then forgetting about it. Or it can happen by another application or bug enabling the Software Restriction Policy.

Furthermore, the “Cannot open the application or program” error message will trigger by a program (such as a third-party security program) that is set to prevent particular apps from launching.
