SEP client installation rolls back at creating install cache.

James is this a root certificate error  why the installation is rolling back? is this showing in the logs ?

Previous SEP version we have received same error That's reason i have provided 2 different articles,But you can try to install latest root certificate.

Is this an upgrade or a fresh install?

on majority of the machines its a fresh install and on others its an upgrade from RTM

Any clue Brian what is happening ?

Not the old cert issue.

How many machines are affected here? Getting some generic errors in the logs.

around 30 -40 mostly 32 bit machines

And you're using the correct package, 32bit for those machines, not 64?

yes brian 32 package for 32 bit machines

Try updating the cert on one machien, see if that fixes..

Any Application and device control policy in place?

It was a corrupt installation package that was causing the installation to rollback and not complete.
