Microsoft Excel Application entry is missing in DCOM Config

问题

The entry for "Microsoft Excel Application" is not there in DCOM Config (tried in both 32-bit and 64-bit). How can I make it shows up there? I have Microsoft Office installed.

If you cannot find 'Microsoft Excel Application' in either 32-bit or 64-bit DCOMCNFG, you might go into registry to HKEY_CLASSES_ROOT/AppID and find the CLSID for your version of Excel (Excel 2013 has an AppID of {00020812-0000-0000-C000-000000000046})

Check that the (Default) REG_SZ for this key has a value set for it.

If not, change the default value to "Microsoft Excel Application" and after relaunching DCOMCNFG you should see "Microsoft Excel Application" in the DCOM tree.

Assuming you have restarted since the install, this page explains how to attempt to re-register the COM server: TechNet Entry on Excel DCOM Config.

From a command prompt, navigate to where the Excel.exe is located and re-register the application. On a 64-bit machine, this is located (by default) under C:\Program Files (x86)\Microsoft Office\Office14 for Office 2010 and C:\Program Files (x86)\Microsoft Office\Office12 for Office 2007.

1. Open a command prompt – START, RUN, type CMD.EXE but don’t hit ENTER just yet
2. Find CMD.EXE in the ‘All Programs” list. Right click it and left click on “Run as administrator”

3. This should open a command prompt. Now, type the following:

   CD\
   

   And hit ENTER. Then type:

   CD C:\Program Files (x86)\Microsoft Office\Office14
   

   And hit ENTER. Then type:

   EXCEL.EXE –REGSERVER
   

   And hit ENTER

* Note, for Microsoft Word the CMD would be: WINWORD.EXE –REGSERVER

Start DCOMCNFG in 32-bit Mode:

DCOMCNFG -32

Then located under:

Component Services \ My Computer \ DCOM Config \ Microsoft Excel Application
