No Text - Hotfix not installing for Educational Inventor 10

[hemo]

Symptom: Looks like the MS update security problem interfering with text entry.

Problem: Hotfix will not install
"This hotfix could not be installed because it is not designed for the version of Autodesk Inventor Professional 10 that is installed on your computer"

Application information:
Full Inventor 10 Professional (Educational Version)
Build: 270, Release: 10 SP2 - Date: Mon 09/26/2005
Service Pack 2

Any help or suggestions?
Thanks

Are you sure you are downloading the correct Hotfix for r10

Also, students can download free Autodesk Inventor Professional 2008 from http://engineersrule.org
(and you would want to download the AOEMViewer Hotfix and Service Packs 1& 2)

Service packs must be installed in order.

Inventor 10 Pro is on SP3a.

The hotfix will only install when all the major updates released before it have been installed.
