ClassFactory cannot supply requested class

This line is failing right off the bat in 9.4 Beta:

IAoInitializePtr ipInit(CLSID_AoInitialize);

C++ must wait for now

C++ support is coming "after Beta 1". Hopefully there will be a linkable library to support the equivalent of VersionManager.LoadVersion.

To use LoadVersion in C++ do the following:

Import the ArcGISVerion.dll

#import "libid:6FCCEDE0-179D-4D12-B586-58C88D26CA78" no_namespace raw_interfaces_only no_implementation rename("esriProductCode", "esriVersionProductCode")

You may have to rename the esriProductCode because it is also in esriSystem. Then add the following line before any ArcObjects code.

IArcGISVersionPtr ipVer(__uuidof(VersionManager));
VARIANT_BOOL succeeded;
if (FAILED(ipVer->LoadVersion(esriArcGISEngine, L"9.4", &succeeded)))
return 0;

You are right, the C++ sdks are currently are not available for Beta 1.

That worked! Thanks,
