Wise Windows Installer v6, test for Registry value
Posted on 2010-11-26
I am using Wise Windows Installer v6 Professional, and need to test for the presence of a specific Registry value and abort the installation if it is not found. I am currently using the Search System option to retrieve the data from the value, which is a path that is saved to [INSTALLDIR].
I need this test becuase I need to abort the installation if a another of my installations programs has not been previously executed, which would have created and set the value that I am testing.
