How to Fix Installer Error 1619
The Windows Installer is used by many software vendors other than Microsoft. In some cases they installer can result in an error while trying to install a software product. One possible error is installer error 1619, with the message “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.”
Basically the installer cannot open part of the installation package. This can be an NTFS access issue, a problem with the downloading of additional install components, or a problem with the Windows Installer version.
Solving Installer Error 1619
The first step is to make sure you have the latest service pack installed on your Windows version. This should ensure that you have the latest Windows Installer. If you still have problems with the Windows Installer, try downloading and installing the latest Windows Installer version manually.
Updating the Windows Installer should also fix the access issue, where the user does not have the proper right in the NTFS folder that is used by the installer. If it does not help, check the access rights for the current user in the installation folder, or log in as a user with administrator rights and try the software install again.
When the installer is trying to download additional installation components from the web, like the Java Runtime library, installer error 1619 can mean problems with the Internet access. So always check the firewall settings in those cases, and ensure the installer has web access. This is most common with the Microsoft firewall actually.
There is one more possibility for installer error 1619 to occur when you try to install an application that was developed with Visual Studio .NET with Web Bootstrapper settings, but for that please check the Microsoft Knowledge base article as it is rather specific. The issue is still that an installer package can not be downloaded though.
When an installation fails, please make sure you uninstall or remove the failed installation first, because many successive installation problems can be the result of a failed initial installation. So when upgrading, always consider uninstalling an older, existing version first.
