same issue working on Visual Studio 2010 installer but install shield has failed to get install path during installation using

UINT gp = ::MsiGetProperty( hInstall,
                               _T("CustomActionData"), 
                               customData, 
                               &len);

Answer 1

You need to change the name of your property that you are setting from CustomActionData to the name of the deferred custom action that will receive the CustomActionData. In this case that would be CustomActions.

Answer 2

The problem is: You did not add Property using Property Manager.

1. You need to custom action in InstallShiled.

   

2. You need to add "New Set Property" in Custom Action Section.

3. You need to fill up information of "newly Set Property" in Custom Action Section.

4. Property Name = Custom Action Name

   Example:

   Property Name = "Installation"

5. You need to use "CustomActionData" in C++ MSI DLL Source code.

   Example:

   MsiGetProperty( hInstall, _T("CustomActionData"), customData, &len);
