I’m writing a C# program that acts as a PowerPoint 2007 plugin. On some machines, some calls to the PowerPoint object model throw a COMException with the message RPC_E_SYS_CALL_FAILED. I couldn’t find any specific advice on what to do regarding this error, or how to avoid it. From Googling it looks like something to do with the message queue or Single-Threaded Apartments. Or am I way off?
Example of the error message is:
System call failed. (Exception from HRESULT: 0x80010100 (RPC_E_SYS_CALL_FAILED))
at Microsoft.Office.Interop.PowerPoint._Presentation.get_FullName()
Unfortunately, the problem is occurring on a client’s machine, so I have no easy way to debug it! Should I just retry the calls whenever I get this error?
Any advice to help me resolve this problem would be greatly appreciated!
