How do I get the installation destination path in a deferred custom action for a Basic MSI project? I'm trying to get the value of INSTALLDIR, but I just get an empty string. Is there a simple way to do this?
I'm pretty new to InstallShield but I just implemented what you'd like to do. What I did was create a property and then I set that property to INSTALLDIR in a custom action. I then accessed this property in an InstallScript using the MsiGetProperty with "CustomActionData" parameter. The key in implementing this is to name your InstallScript function that same as your property.
Okay thanks. It was a bit confusing, but I eventually got it to work.
But what if I wanted to get both INSTALLDIR and SUPPORTDIR for use in the same InstallScript function? I believe I saw a help article on doing this in VBScript using arrays. Would I do it similarly in InstallScript? What would I name the Custom Action since I am getting more than one property?
