Windows 7 & Vista Help

Issue:

L-Measure Online version Applet gives an error "java.io.FileNotFoundException (Access is denied)" in Mozilla Firefox on the systems of Windows Vista and Windows 7.

Solution For Windows Vista:

Turn off the User Account Control (UAC) setting as follows:

Control Panel->User Accounts->Turn User Account Control on or off.

Solution For Windows 7:

Turn off the User Account Control (UAC) setting as follows:

Control Panel->System and Security->Action Center->Change User Account Control setting

Adjust the slider to the bottom most level.

Alternate Solution:

Go to the executable for browser one is using, for example 'Program Files\Mozilla Firefox\firefox.exe' then right click the executable, one will see a tab that says 'Run as Administrator'.

One can run jnlp or a web based application as administrator and it won't be prone to virus attacks as it gives admin access only once.

Rational:

*User Account Control* (*UAC*) is a technology and security infrastructure introduced with Microsoft's Windows Vista and Windows 7 operating system.

It aims to improve the security by limiting application software to standard user privileges until an administrator authorizes.

Due to this reason, the application will not inherit administrator privileges unless the user explicitly authorizes it. Hence the application gives an error because it needs explicit authorization.

Implications:

When changes are going to be made to your computer that requires administrator-level permission, UAC notifies you. Because the UAC is turned off, applications will not ask for permission to execute. Hence the administrator should be careful while running applications.
