Purpose
If you have the responsability to patch an heterogeneous environment made of Operating Systems and applicatiosn in different languages you will need to define the languages of the patches you will download and then deploy.
Enable other languages
If you want to enable languages other than English, you have to specify it in Tools > Options > Patch Languages
There, you specify the default languages of your patches that you will download.
When you have defined those settings (in our example English and French), when you download a patch Protect will download the english version and the french version if available.
Download a non-english patch
Go to the Patch View, select a patch and right-click "Download".
A window will summarize the languages that were defined previously. However, if you don't want this window to pop-up each time, tick the box "Save the checked languages as the defaults".
Click Download, and you can follow the download progress in the Shavlik Protect Operations Monitor, as illustrated below :
