HomeTroubleshootingInstallation"This installation package could not be opened."

1.30. "This installation package could not be opened."

I'm trying to download and install your software, but the installer puts up this message and refuses to run:

This installation package could not 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.

Please verify that your browser considers the download 100% complete before you start the install. 

If the download is 100% complete and you get this message, most likely there is a problem with the Windows Installer Service on your computer.  Either the service is disabled (blocked from running), or one or more of its files are corrupted.  Please visit Microsoft's article How to Troubleshoot Windows Installer Errors and follow the instructions there.  If you're unable to complete the instructions there, you may need to have your IT department run the procedure for you or unblock the Windows Installer Service.

If you have successfully repaired the Windows Installer Service and still have a problem with the install, please contact Palisade Technical Support.
