Install issue - This package could not be opened

Hi, I can’t install the eM Client because I get the following “This package could not be opened . Contact the application vendor to verify that this is a valid Windows installer package.” I am running Windows 10 Professional 64 bit.

Please advise.

windows installer

Can you try using the current release here

Yeah apart from trying the latest current release as @sunriseal advised, also check that the “Windows Installer” is running as per the below Microsoft website link.
