Do you have an idea why this error occurs?

We tried different location and deactivated the windows firewall, which did not help. Also playing with the security settings of mozilla did not work out. However, the good news is, that using the explorer the subject had not problems at all. So, if someone experiences the same error message, this might be a solution.<br/>Best<br/>JuliaTue, 03 Nov 2015 02:18:34 GMTjuly1810https://forums.millisecond.com/Topic17419.aspxThis looks like the error is coming from the web player installer. The download might have been corrupted or the person is executing the installer from a location with insufficient permissions. In the latter case, moving the installer to a different location and executing from there should help.<br/>Mon, 19 Oct 2015 01:07:31 GMTDave
