I can push Agent 4.0 from EPO 3.6.0 to a Win & client but not the AV8.7. deos not give any errors anyone have this problem?
From the Installation Guide for VSE v8.7i, it states that the minimum supported version of ePO is v3.6.1.
You are using ePO v3.6.0 which has gone end-of-life as of 31-Jan-08. See http://www.mcafee.com/us/enterprise/support/customer_service/end_life.html
Since ePO v3.6.1 is end-of-life 31-Dec-09 (or in 17 days as of this writing) you might want to consider upgrading to at least v4.0 or even v4.5. Make sure you apply whatever patches are available. Then, follow the directions as indicated in whichever version of ePO you decide upon.
Hope this is helpful.
