Desktop Central MSP - Upgrade

Desktop Central MSP - Upgrade

I have the following version of ME Desktop Central 9:

Product Details
 Product: ManageEngine Desktop Central MSP 9
 Company: ZOHO Corp
 Version: 9.1.0
 Build No: 91122

I'm trying to upgrade to 9.2, but keep getting ppm file is not for your build. I've tried both of the following files:

ManageEngine_Desktop_Central_MSP_9_SP_1.ppm
ManageEngine_Desktop_Central_MSP_9_2_0_SP-0_027.ppm

When I looked at the download location it doesn't list 9112 as a version to upgrade from:

Migrate from 
Build 91000, 91001, ......, 
91121
to Build 92004

So, how can i Upgrade 9.1.0 - 91122 to 9.2?
