Java Installation ProblemsJava is a free addition (plug-in) for all operating systems, including Windows, Mac or Linux/Unix.

There are usually a few outstanding known issues in Java, which is open-source and constantly being improved. We try to anticipate and help manage these rare issues when possible until fixes are included in the next release of Java. Information on known Java installation issues is here. If you are experiencing problems installing Omniscope please submit an issue report. Freezing or HangingIf you experience hanging with no Omniscope error message displayed, first consult the list of known Java issues below, some of which you can resolve by updating your version of Java. Known Windows and Java issues:1. Windows and Java do not allow file names with '?' or other special characters such as '*' in the file name- if you use a '?' or '*' or other special characters when you specify the file name, nothing will happen. Try saving the file with a different name not including unusual characters. If your installation opens normally, but at some point experiences hanging or freezing, and you do not see an error message, and you are not experiencing a known Java problem outlined above, please follow the hang diagnosis procedure . Functions requiring Internet accessAutomatic activation, updating and bug reporting functions all depend on Visokio applications being able to access the Internet. Firewall settings and addiional machines between your machine and the Internet called Proxy Servers can interfere with the ability of the Visokio application to access the Internet. In general, correct Proxy Server configuration will ensure that all functions are available. If not, in each case, there are work-arounds available:
