1. If ePO 4.5 Patch 3 is not visible with your grant number you need to speak to McAfee Customer services, as it's definitely been posted.
In order to go to 4.5 from 4.0sp7 you have to install 4.5 sp3 install. It will not upgrade if you are trying to upgrade 4.5 sp1 or 2, it has to be sp3 if you are on sp7. But if you do not see that thenis corect, you will need tot talk to McAfee.
you are looking for epo 4.0 patch 3, and i don't see it on the mcafee site either... i see patch 7 or the base install.
Since you need it to prep for 4.5, I would hope they would repost it.
You should be able to go to EPO 4.0 P7, and then upgrade to EPO 4.5 P3.
Issue: ePolicy Orchestrator 4.0 Patch 7 cannot be upgraded to ePolicy Orchestrator 4.5, ePolicy Orchestrator 4.5 Patch 1, or ePolicy Orchestrator 4.5 Patch 2, due to incompatible versions of Java Runtime Environment (JRE). (Reference: 559217)
Workaround: When upgrading to ePolicy Orchestrator 4.5, upgrade to ePolicy Orchestrator 4.5 Patch 3 or higher.
As Mal09 says. Upgrade path = ePO 4.0 Patch 7 -> ePO 4.5 Patch 3
