the ppm you specified is not compatible

the ppm you specified is not compatible

I am running Desktop Central MSP 7 build 70211.  I downloaded the latest hotfix ManageEngine_Desktop_Central_7_0_0_SP-2_24.ppm.  When I use the Update Manager to try to update I get
Error - the ppm file that you have specified is not compatible with this product. 
Help!
