ROES and Windows 8 Update


As Windows 8 begins to grow in use, ROES does continue to run well under most circumstances. Since our last update on Windows 8’s release date, we have tested on 3 new Windows 8 installs, in all of which ROES was able to run immediately after installing Java 7 from There have been several items of note, detailed below with resolutions:


1) Desktop Icons Appear White – This is a known Java issue and is resolved with an upcoming Java release, Java 7 update 12 (expected next month, available at


2) Launch Failure – The Kaspersky Internet Security 2013 suite prevented the launch.jnlp file from being properly downloaded and executed. The Details of the Java error indicated ‘Unable to load resource’ and listed the URL path to the jnlp file. Disabling Kaspersky allowed it to function properly and launch from the web link, and after re-enabling the security application’s scanners ROES launched normally from the desktop icon.
3) FTP Send Failure – This was seen on the same system with FTP, Java 7 and Kaspersky Internet Security 2013. Unfortunately, disabling Kaspersky did not help. However, uninstalling Java 7 and installing the latest Java 6 update 64 bit instead (available at, use the Windows x64 link after going to JRE) allowed the send to occur.


4) Launch Via Web URL Fails (Win 7 and 8) – In 2 instances we have seen an issue where repeated Java installs/uninstalls between 6 and 7/32 and 64 bit leave the file association for jnlp in limbo. In normal cases, this can be resolved by changing jnlp’s default application via either Default Programs in Control Panel or by right-clicking the jnlp in Downloads or the Desktop and selecting Properties, then navigating to the javaws.exe file via the Change button. However, in these instances Java Web Start would not list in the available programs list to set as the program. The only way the association was fixed was via the regedit command, using Edit – Find to search for jnlp and changing the path for the default program in HKEY_CLASSES_ROOTjnlp_auto_fileshellopencommand. The path listed showed a 32 bit (Program Files (x86) Java folder path to javaws.exe that no longer existed. Manually editing this value to the proper Java 7 path allowed the jnlp to be executed properly.


We will be continue to monitor Windows 8 performance for any other issues, as well as evaluating tablet use such as the available Samsung Win 8 device, and upcoming Microsoft Surface Pro and HP ElitePad, all of which run full versions of Windows 8 and should allow normal Java installations. Updates will be posted to the sites at and
