我启动HostApplication的时候会报一个错,
{"Value cannot be null.\r\nParameter name: pUnk"}
at System.Runtime.InteropServices.Marshal.GetTypedObjectForIUnknown(IntPtr pUnk, Type t)
at AspenTech.AspenSCM.integration.VSTAHookup.CreateTypeInfrastructureManager()
at AspenTech.AspenSCM.integration.VSTAHookup..ctor(IDispatch* pApp)
at AspenTech.AspenSCM.integration.VSTAHookup.GetInstance(IDispatch* pApp)
at StartVSTA(IDispatch* pAppl)
有谁知道是为什么吗?好像是VSTA不能启动,那会是哪里出错了呢,先谢谢大家了
