Hi everyone:
My company need to upgrade all SEP clients to newest version - 12.1.4100.4126 and migrating all existing clients to a new SEPM server. Until now, most of Workstaions/Servers installed successfully except one printing server with operating system: Windows Server 2008 Standard SP2.
I have tried to remote push the installation package from new SEPM server, but it return an error message "Fail to install, rollback to old version" on the console. Also, I exported the installaiton package and copied into the printing server, it failed again without any error message.
Instead of the version 12.1.4100.4126, I tried to installed the older verison: 12.1.1101.401 RU1 MP1, it was successful to install.
Thus, I tried to upgrade SEP from 12.1.1101.401 RU1 MP1 to 12.1.4100.4126, something critical happen to printing server: The firewall module could not be loaded, and the network driver unable to start, thus I uninstalled the SEP and the network driver can be started up again.
But in my testing environment, I want to reproduce that issue by the following steps:
1. Install SEP 12.1.1101.104 RU1 MP1 on Windows Server 2008 Standard SP2 - Success
2. Exported and copied the SEP 12.1.4100.4126 installation package to Windows Server 2008 - Success
3. Directly install SEP 12.1.4100.4126 without uninstalling old version - Fail(Nothing happened to network driver, just fail to install)
I checked the SEP 12.1.4100.4126 supporting platform from here, Windows Server 2008 SP2 was listed.
Please help. many thanks.
