We would like to ask our free license users to upgrade Remote Utilities to version 6 until August 10, 2015. Your license will still be free as it has always been - you only need to upgrade the program itself. Starting August 10, 2015 access to our Internet ID servers for old versions (i.e. 5.x and older) registered with a free license key will be restricted.
This upgrade is a part of our plan to further improve the security of our software and make it less prone to being falsely detected as malware by antivirus programs. In version 6 we implemented mechanisms that made it a lot harder to tamper with RU files and use the program for malicious purposes undetected. In addition, version 6 has a lot of improvements and bug fixes and is more stable overall. See the Release Notes.
Follow this tutorial in order to upgrade your installation. If you are a paid license user of version 5.x and you want to continue using that version, you do NOT have to upgrade. Nothing will change for you. However, we still recommend that you upgrade to version 6.
