This is caused by attempting to run an old version of Language Lab on a system with Windows UAC, such as Vista, Windows 7 or Server 2008.

In the short term, you can get the program to run by right-clicking the EuroTalk Network Manager icon, and selecting “Run as Administrator”.

In the longer term, we strongly suggest updating to the latest version: please call +44 20 7371 7711 or email us on education@eurotalk.com.
