Thanks; that was my understanding too. We have a situation where the same app codebase will be deployed to 32bit in some cases and 64 bit in some cases and can't have separate build/deployment procedures. So it now appears that our only option is to move to ChartFX 7.

Will this 64-bit unmanaged version (ChartFX 6.2) run under both 32 and 64 bit ?

My interop assembly is compiled for "AnyPlatform". The interop is written to run as a COM+ serviced component and has a reference to the ChartFX Internet 5.5 COM component.

Hi I had a .net 2.0 web app that was using an interop assembly (references chartfx) . This assembly is used in some pages to generate chart images. This was working well when IIS was running in 32 bitmode. Now we are migrating to native 64 bit and are facing issues with these pages that use charting. I get the following error: System.Runtime.InteropServices.COMException (0x80040154): Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)) at System.Runtime.InteropServices.Marshal.ThrowExceptionForHRInternal(Int32 errorCode, IntPtr errorInfo) at System.EnterpriseServices.Thunk.Proxy.CoCreateObject(Type serverType, Boolean bQuerySCInfo, Boolean& bIsAnotherProcess, String& uri) at System.EnterpriseServices.ServicedComponentProxyAttribute.CreateInstance(Type serverType) at System.Runtime.Remoting.Activation.ActivationServices.IsCurrentContextOK(Type serverType, Object[] props, Boolean bNewObj) Is there a way to get this to work for 64 bit ?
