Cannot create COM object from ASP.NET (Creating an instance of the COM component with CLSID {} from the IClassFactory failed... error: 8007000e)

I have an API DLL which is a COM object. I’ve used this DLL in a Winforms application successfully. When I use it in ASP.NET application I get the E_OUTOFMEMORY error: “Creating an instance of the COM component with CLSID {} from the IClassFactory failed due to the following error: 8007000e” when I create an instance of the COM object.

Although I don’t think it is a security issue, I’ve tried using windows authentication and also to give privileges to the ASPNET user with no use.

I don’t have the source code of the COM object. I'm using .NET Framework 3.5.

Thanks in advance, Sharon.开发者_如何学运维

Visual Studio / Tools / Error Lookup reveals:

"Not enough storage is available to complete this operation."

This isn't necessarily an OOM exception, I've had cases in serialization where deserializing the object size silently failed returning -1, and the subsequent allocation failed with an OOM exception (because usually (unsigned)-1 == all memory except one element).

After hours of investigation we found that the problem is in the API.

Thanks for everyone.

Sharon.
