Issue with launching Excel running programme in c#

Question

When I try to run a programme in MS visual studio to start excel in the background on my desktop, the two error windows pop up.

Window 1:
Assertion failed!
Program: ...\Microsoft Office\Root\Office16\AppVlsvSubsystems32.dll
File ..\ComRegistry.cpp
Line: 191

Expression: TokenElevationTypeLimited != elevationType

For information on how your program can cause an assertion failure, see the virtual C++ documentation on asserts.

(Press Retry to debug the application - JIT must be enabled.)

Window 2:
Retrieving the COM class factory for component with CLSID {000-24500-0000-0000-C0000-0000000046} failed due to the following error: 8008005 Server execution failed (Exception from HRESULT: 0x80080005 (CO_E_SERVER_EXEC_FAILURE)).

The error arises only when subprogrammes which call excel are run.

The command which call Excel to start is as follows: Microsoft.Office.Interop.Excel.Application xlapp = new Microsoft.Office.Interop.Excel.Application();

The version of software installed to the desktop are as follows

• Visual Studio Version: MS Visual Studio express 2015 for windows desktop (ver. 14.0.25123.00 update 2)
• Excel Version 2002 (Built 12527.21330 Click to Run)

Hi JasonLau,

>Program: ...\Microsoft Office\Root\Office16\AppVlsvSubsystems32.dll

It seems that your program should work with office 2016 instead of 2002.

>(Press Retry to debug the application - JIT must be enabled.)

Please try to go to Tools/Options/Just-In-Time, then enable all types:

>The command which call Excel to start is as follows: Microsoft.Office.Interop.Excel.Application xlapp = new Microsoft.Office.Interop.Excel.Application();

Please have a try to use Microsoft.Office.Interop.Excel.ApplicationClass Class to call excel app in your C# code

Best Regards,
Dylan

Thanks for your reply, but the JIT option cannot be found in the Options tab.
