I have an issue with building an MSI with Install Shield LE in Visual Studio. The error says "-4340: Internal Build Error", but the link to Flexera is worthless. I tried the suggestion in another post to add the installer project to a fresh solution and then my .Net projects after, but that did not help. That suggestion can be found here.
I have not found a single repeatable cause of the issue, it does not seem to happen because of any one thing. I'm trying to build an installer for a Windows Service.
I got that error too. In order to fix it i rebuild my solution in Release configuration instead of Debug one.
