Get ProductVersion in BasicMSI Custom Action
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:
Any advice?
Thank you.

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.
