hi Ingo,

i didn´t search because i didn´t know how do it.

changing application pools to 32bits solve the problem. But which is the reason that the activex 64bits is not recognized by VS2017 or by IIS? but 32 bits is recognized. I want work with 64bits. There is a problem with 64bits activex dll.

I will search for a thread about "problems registering 64bits activex dll", if i don´t found i will open it

Thank you so much.

The real problem is with activex 64bits dll, there is a problem registering, because neither VS2017 nor IIS recognize the dll and gives an clsid error. We can`t do the project with 32bits because IIS works with 64bits.

When we register the 64 bits activex dll, the administrador window of cmd returns "Dllregisterserver runs ok in DebenuPDFLibrary64AX1811.dll" but the activex object is not installed in windows.

Thanks & Best Regards.

We are trying to create an asp webservice project with vs2017 and dll unmanaged, but we have problems with iis and unmanaged dll. You can see this problem in
https://stackoverflow.com/questions/44455559/iis-and-external-unmanaged-dll
https://amithegde.com/2015/06/fixing-unmanaged-dll-not-found-exception-on-asp-net-app.html

then we try with activex dll, we register the 64bits activex dll, but vs2017 cant load in com references, but if we register 32bits we can load at com references. Then we try without load com, and importing the file in imports folder, "DebenuPDFLibraryAX1811.cs". The function Type.GetTypeFromProgID("DebenuPDFLibrary64AX1811.PDFLibrary") returns the type but when we call Activator.CreateInstance(comType) returns :

No se pudo recuperar el generador de clases COM para el componente con CLSID {480150A0-2BD1-4C97-820B-009527B9E883} debido al siguiente error: 80040154 Clase no registrada (Excepction HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))

Thanks & Best regards.
