Corrupt Setup: IFCEngine
If you get an error message when starting Simplebim that says “The application cannot start because the setup is corrupt (IFCEngine). Please make sure to run a setup installed using a valid installer.”, then this is most likely because a library is missing or it is blocked.
IFCEngine is using a Microsoft C++ library that is installed by Simplebim. However, when you get the message above, this library is either missing or Windows or a firewall doesn’t accept it. This issue can be fixed by installing this library separately using the original Microsoft installer, which you can get at https://www.microsoft.com/en-ie/download/details.aspx?id=48145
Simply install the C++ library using this Microsoft installer and start Simplebim again.
