failed to register. HRESULT -2147220473. Contact your support personnel
Solution:
Try registring the dll manually by using regsvr32 command
CMD> regsvr32 C:\Oracle\Middleware\EPMSystem11R1\products\Essbase\EssbaseClient\bin\essegd.dll
If that does not pass through apply following patch:
The patch has a new set of installers use it, follow the readme.
Reason: Could be due to already existing EPMSystem setup already existing and some of the files that were missing during the setup. Not very sure why the error but the patch does speak there was a bug reported
