We tried to update Service Desk Plus from build 7500 to 7514.

I've dowmloaded the pack from there:

http://www.manageengine.com/products/service-desk/service-packs.html

Then I launched the UpdateManager.bat clicked on browse and picked the file ManageEngine_ServiceDesk_Plus_7_5_0_SP-0_14_0.ppm 

There I have an error message : "The file that you have specified is not compatible with this product". (see print screen)

I checked the version of the software: it's the build 7509 (see print screen #2)

Could you help me with this problem please? Is a licence needed for these updates (see print screen #3)?

Thank you,

Fabrice
