I get this error when I try to load it in ArchiCAD (demo mode):
The file is either not an Add-On or an outdated one that cannot be used with this ArchiCAD version.
Could VS 2008 be the issue?
Definitely. Please refer to the
in the API Documentation:
On Windows you need Microsoft Visual C++ .NET 2003 installed.
From AC12 onward, you need VS 2005. Do not use VS 2008 for any ArchiCAD API development.
