E2007 sp3 reollup13 applied but not showing in version

Hello,

i've installed a FRESH NEW exchange 2007 standard SP3 x64 on a fresh new win2008R2,

the version out of the box is:

Edition             : StandardEvaluation
AdminDisplayVersion : Version 8.3 (Build 83.6)

i then applied update rollup 13 KB2917522 x64, it applies OK, even shows in add/remove programs but the version stays the same!.

i've checked it in the console as well, the version should be 08.03.0348.002

what's going on?
