Violation of primary key constraint pk_modelelementdata_elementhandle

Hi,

I am trying to install a new microsoft hotfix for DAX2012R2 CU7. But a below error occurred while installing the hotfix.

AxUtil call returned errors:
Violation of PRIMARY KEY constraint 'PK_ModelElementData_ElementHandle'. Cannot insert duplicate key in object 'dbo.ModelElementData'. The duplicate key value is (892320, 1).
The statement has been terminated.

I followed the below blog and requested an hotfix.

But I did not get any hotfix email from Microsoft. Is there any other way of handling this issue?

Thanks,

Lakshmi
