We are striving to upgrade our Desktop Agent to from what is
currently a mixed bag of 4.0.1 upwards.

Our desktop environment is XP Sp2. ALL users only have User permissions to
the local environment. This is a constant that cannot change.

Whilst trying to use NAL to update the ZdM Agent, an MSI error 1603 is
being encountered. MSI logging reports this error is related to
insufficeint priveleges to perform the installation. The NAL object is user
associated and is set to force cache. Manipulation of the unsecure/secure
system user switches do not solve the issue. Logging in with a user with
elevated priveleges performs a successful install.

Is there a method to use NAL to install the ZdM Agent in a User
permission-level environment?
