Server execution failed (Exception from HRESULT: 0x80080005 (CO_E_SERVER_EXEC_FAILURE))

Question

I am trying to convert a .xls file to an .xlsx file on the server-side using Microsoft.Office.Interop.Excel.Workbook class as follows:

 workBook.SaveAs("FILENAME_HERE", XlFileFormat.xlOpenXMLWorkbook, Type.Missing, Type.Missing, Type.Missing, Type.Missing, XlSaveAsAccessMode.xlNoChange, Microsoft.Office.Interop.Excel.XlSaveConflictResolution.xlLocalSessionChanges, Type.Missing, Type.Missing, Type.Missing, Type.Missing); 

and I get the following error:

Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80080005 Server execution failed (Exception from HRESULT: 0x80080005 (CO_E_SERVER_EXEC_FAILURE)). : System.Runtime.InteropServices.COMException (0x80080005): Retrieving the COM class factory for component with CLSID {00024500-0000-0000-C000-000000000046} failed due to the following error: 80080005 Server execution failed (Exception from HRESULT: 0x80080005 (CO_E_SERVER_EXEC_FAILURE)).    at System.Runtime.Remoting.RemotingServices.AllocateUninitializedObject(RuntimeType objectType)    at System.Runtime.Remoting.Activation.ActivationServices.CreateInstance(RuntimeType serverType)    at System.Runtime.Remoting.Activation.ActivationServices.IsCurrentContextOK(RuntimeType serverType, Object[] props, Boolean bNewObj)    at System.RuntimeTypeHandle.CreateInstance(RuntimeType type, Boolean publicOnly, Boolean noCheck, Boolean& canBeCached, RuntimeMethodHandleInternal& ctor, Boolean& bNeedSecurityCheck)    at System.RuntimeType.CreateInstanceSlow(Boolean publicOnly, Boolean skipCheckThis, Boolean fillCache, StackCrawlMark& stackMark)    at System.RuntimeType.CreateInstanceDefaultCtor(Boolean publicOnly, Boolean skipCheckThis, Boolean fillCache, StackCrawlMark& stackMark)    at System.Activator.CreateInstance(Type type, Boolean nonPublic)    at System.Activator.CreateInstance(Type type)    at CALLING_METHOD_IN_MY_LIBRARY_HERE... 

The problem is that this error occurs only on the staging server; on my local machine it works fine.

Things that I have tried on the staging server:

1. **1) Run dcomcnfg open Component Services

2) Expand Component Services "->" Computer "->" My Computer "->" the DCOM configuration "

3) Find the "Microsoft Excel application."

4) Right to open the Properties dialog box

5) Clicked on the "Security" tab,

6) "Launch and Activation Permissions, configure permissions, have added permissions - Identity run under Adminstrator user (This User), Interactive User and Launching Users

7). Launch and activation permissions + Access Permissions + Configuration Permissions => added IIS_IUSRS + Network Service with Full Controll**

2. Changed the build of the project that converts the .xls file from "Any CPU" to "x86" on my local machine and published this library on the server.

Did someone figured out how to fix this problem? I am struggling on fix this issue for 2 days now.

Answer 1

Using DCOMCNFG.exe. Open it and go to: Component Services -> Computers -> My Computer -> DCOM Config -> Microsoft Excel Application.

Open the properties, select Identity tab and select the interactive user.

Answer 2

I found the solution elsewhere.

Doing the following did solve my problem:

Using DCOMCNFG.exe. Open it and go to: Component Services -> Computers -> My Computer -> DCOM Config -> Microsoft Excel Application. Open the properties, select Identity tab and select the interactive user.

BUT - the problem came back every few minutes !

After hours of trying to figure out the cause, I noticed my server had hundreds of opened WINWORD.EXE processes. This caused a memory issue which leaded to the exception from hresult 0x80080005 error.

Well, stupidly enough, I forgot to write the code to close the interop application. Once I fixed that, the error was gone.

doc.Close(false); Marshal.ReleaseComObject(doc); word.Quit(); Marshal.ReleaseComObject(word);
