What Causes “The Installation Package Could not be Opened” Error?

After receiving numerous reports from multiple users, we decided to investigate the issue and devised a set of solutions to fix it completely. Also, we looked into the reasons due to which it is triggered and listed them as follows.

  • Installation Service: This error is caused by the installation service being stopped, the service is responsible for installing all packages on the computer and if it is stopped the installation of the packages is also prevented.
  • Administrative Privileges: Some installation packages might require special permissions from the administrator to install them. If these permissions aren’t provided this error might be triggered for the installer.
