Communication between a Custom Action and its MSI
Presently I'm trying to install a third party application during the install of my MSI on the desktop. Problem is, that the third party application, which was built in Install Shield 6, did not come with the ability to make an appropriate ISS script for it's automation. So at present, I'm using a combination of Visual Basic 6 and the AutoIT DLL to automate the install.
At present there is no cause for concern, but on the off chance that something goes wrong with the automation I've encoded the ability for the visual basic program to terminate itself. Problem is I then want to tell the MSI that installation failed and to begin rollback; as the MSI will still register this custom action as completing successfully. How do I do that (please include example code)?
