LiberKey is a Windows tool for managing portable applications.
According to the forum post referenced below, this is a safeguard intende to prevent corruptions of configuration files if multiple instances are run.
This protection can be disabled (if you accept the risk) by adding a line in the config file "\LiberKeyTools\LiberKeyMenu\LiberKeyMenu.xml":
<Config>
...
<EnableNetworkStart>yes</EnableNetworkStart>
</Config>
