Get ProductVersion in BasicMSI Custom Action

[san_bsw]

Hi,

is it possible to get the ProductVersion in a Custom Action using a BasicMSI project?

The ProductVersion is always empty.

Even in an InstallScript the ProductVersion property is empty. I tried the following code:

function MyFunction(hMSI)
    // To Do:  Declare local variables.
    STRING svResult;
	NUMBER nvSize;
begin

    // To Do:  Write script that will be executed when MyFunction is called.
	nvSize = 256;
	MsiGetProperty (ISMSI_HANDLE, "ProductVersion", svResult, nvSize);
	MessageBox (svResult, INFORMATION);
end;

Any advice?

Thank you.

If your custom action is deferred, you'll need to use the CustomActionData property to obtain the value of a property such as ProductVersion. To learn more, see Accessing or Setting Windows Installer Properties Through Deferred, Commit, and Rollback Custom Actions.
