I am getting this <<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>>
Yesterday I clean uninstalled my photo editing programs, Photplus X4 and PanoramaPlus, which are similar to Adobe Elements. The reason was that certain pics would not display, although displayed elsewhere.
This morning my attempts to reinstall from the manufacturer's
DVD Rom were unsuccessful with the above error.
Is anyone able to help me, please?
