Something must have gone wrong with invoking the compiler from our install script. Please contact us by email and provide the installer log file (generated under \My Documents) so we can inspect what exactly went wrong.
The Unit Scope Names (vlc, vlc.imaging, etc) where not set in TMSWebGMapsPkgDEDXE10 in the release-configuration of the project. In the debug-configuration it was set.
This caused a error while compiling UWebGMaps.pas:
UWebGMaps.pas(27): error F2613: Unit 'OleCtrls' nicht gefunden.
I added the scope names to the release-configuration and recompiled the project.
