Hello,
I have issue when upgrading sep client from version 12.1.2(2015.2015) to version 12.1.6 (12.1 RU6 MP5) always show "Rolling back install" while booting up client (Windows 7 Enterprise SP1). I already check "SEP_INST.LOG" on target client is look like install successful.
Testing Solution:
Upgrading Source | Result | Remark |
SCCM2012 | Can’t Upgrade | Install SEP completed but it’s rollback to old version after restart client |
IIS | Can’t Upgrade | Install SEP completed but it’s rollback to old version after restart client |
Push Deployment Wizard | Can’t Upgrade | Install SEP completed but it;s rollback to old version after restart client |
Manual Install SEP without Remove old version (exe file) | Can’t Upgrade | Nothing happen when setup.exe *32 process end, It still old version |
| Manual Install SEP with Uninstall old version | Upgrade Successful | SEP Client are upgrade to new version |
