Microsoft Excel Application entry is missing in DCOM Config
c#, com-interop, dcom, excel-interop, office-interop
Solution
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.
Problem
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.
