Effects of Security on Presentation Client Upgrades

The JADE thin client and installer make use of the JADE directory structure described in the previous section to perform their operations.

If the JADE thin client is installed into an unrestricted area, configuration and running of the presentation client and application server work with no modifications required to the operational procedures.

If JADE is installed in the \Program Files directory (or \Program Files (86) directory on a 64‑bit machine with 32‑bit JADE binaries):

• If UAC is disabled for standard users, the thin client upgrade will fail because of lack of permissions.

  For administration users, the necessary privileges are automatically granted so the upgrade will succeed.

• If UAC is not disabled, administrative users are prompted with an Allow or a Cancel choice, but standard users must know and supply the user name and password of a user with administration privileges to enable the upgrade to succeed.

Read-only data and executables are separated from the created, updated, and deleted dynamic files. The use of data directories for each user is not required for the operation of a presentation client, but can be used for applications.

When running JADE in thin client mode, if the presentation client is installed:

• Under the \Program Files directory (or the \Program Files (x86) directory on a 64‑bit machine with 32‑bit JADE binaries), when an automatic presentation client upgrade occurs, you must have administrator rights or know the user name and password of a user with administrator rights. (This is a normal Microsoft requirement that updating of files under the Program Files directory requires administration privileges.)

• Outside of the \Program Files directory (or the \Program Files (x86) directory), privilege elevation to perform an automatic thin client upgrade is not requested.
