When you’re attempting to install a software, the installation begins and soon closes with an error message:
This installation package cannot be opened. Verify that the package exists and that you can access it, or contact the application vendor to verify that this is a valid Windows Installer Package.
As the error clearly indicates, there is a problem accessing the installation package contents. In most of the cases, this issue arises when the package contents are corrupted, missing or your hard drive is failing.
