WiX: Passing Install path to managed custom action

Question

new Day, new Problem;-) Still got to struggle with managed custom action. I already managed it to call an custom action and passing some test data to it. Now I want to replace the testdata with the real data i need. And here the problems starts: I want to call a batch file which was installed in a subdirectory of my installation. Therefore i need to pass the installation path to the custom action. Afaik this can be done using the customactiondata mechanism. But this does not work. When I log the installation I can see that outside of the customaction INSTALLLOCATION is pointing to the correct path, but as soon as i look in the customaction the customactiondata property is empty... What am I doing wrong? Merge Module which calls the custom action: ```

Accepted Answer

If you delineate your data like ... ``` ``` You can access the data like: ``` string property0 = session.CustomActionData["Property0"]; string property1 = session.CustomActionData["Property1"]; string property2 = session.CustomActionData["Property2"]; ``` In the previous example you would use: ``` ``` then ``` string cad = session.CustomActionData["INSTALLLOCATION"]; ```
