In summary, you do not need to specify a URL or download link. The easiest way is as follows.
You can manage the connector installation in the main vWorkpsace console under
Connector Management | Installation
For example, type simply
Then make sure all your brokers have the Vasclient32.exe installer located under the following folder:
C:\Program Files (x86)\Quest Software\vWorkspace\Connectors
The same process would be true for Mac Connector too.but with a different (*.DMG) filename.
When the end users goto the web access site, it will look for an installed client, if it doesnt find one, the web access site will check that Vasclient32.exe exists on the broker and will push to the client. If the client is using Internet Explorer it will use a oneclick install if the browser is not IE it will download the file (from WebAccess, fetched from the broker)
