Distribute NSL 6.1 via Zen

Hello!

I want to distribute NSL 6.1 via Zen (msi-file), but after installing
and reboot following message appears:

SecureLogin may have been configured incorrectly and cannot start.
Please contact your sysadmin. Unable to load access library (madman.dll)

But if i install without Zen all works fine, but we have about 500
workstations, so i have to distribute with zen.

We are using Secret Store,E-directory and NSL 6.1.

I configured nothing specially in this application, so i have also
questions about the parameters of the msi-file.
I found no documentation for parameters of the msi-file for NSL 6.1.

so what are following parameters and where can i found a docu:

allusers
x_installtype
x_istwebclient
installlevel
upgrade
........

there are about 70 entries!

maybe you can help me!

thanks in advance!
