A Praim thin client can be updated using two different type of file:
To download a Praim Service Pack or Hotfix you have to register on the http://www.praim.com site.
A Service Pack is a software that allows to upgrade the thin client firmware from a specific version to the next available version (e.g. "PraimServicePackWE7_1.3.0(1.2.1).exe" will upgrade the thin client firmware from version 1.2.1 to version 1.3.0). If a Service Pack is executed on the wrong firmware it will not produce any effects and the firmware will remain untouched.
A Hotfix is a part of a Service Pack. A Hotfix installed on a specific version will leave the version number unchanged. Hotfix may be suggested from Praim Support people to fix a specific feature on the thin client.
The software upgrade (Service Pack or Hotfix) can be installed using the features offered by ThinMan (see ThinMan guide). You can manually update a single device using the Contextual Menu - Device Update for Windows Embedded (chapter "Praim Service Pack installation / Praim Hotfix Installation") or you can use a Scheduled Activities or Event Activities for automatic installation. The installation file has to be available on the ThinMan Server using the Package Repository.
In both cases pay attention that at the end of the installation a commit will be executed on the thin client. This operation will save all the changes done until that moment, not only the changes done to the installation file, but also all the changes made from the last reboot. A good practice to avoid this and to maintain a clean installation is to reboot the thin client and execute the upgrade accordingly.
Depending on the ThinMan Server license you will be able to perform the upgrading process in different ways:
Refer to the ThinMan Guide chapter Contextual Menu - Device Update for Windows Embedded for manual installation or /WES7/Scheduled Activities and Event Activities for automatic installation. The installation file has to be available on the ThinMan Server using the Package Repository.
