I’ve modified some settings for my wire LAN RDP, but after one day the settings have reverted to Windows 7 Pro x64 defaults. How can I stop this from happening?

My advice is to download the version 3.0.8 (the latest one with Windows 7 support) and then run it as Administrator. The cause of your problem is related to the launch process without Administrator access. Access the download page and install the application, but before doing that, right click the package and select Run as Administrator. Do the same when you start the software for the first time and apply the changes. After this process, those settings will remain.


tried suggested solution but the problem of resetting back to defaults remains

  1. “Enhancements” such as hiding my toolbar by default, burying the hand/select tools in the menu, and also not updating the position of the elevator box in the vertical scrollbar realtime (in a web browser) are incredibly annoying.

  2. The app runs fine, until you try to uninstall it. It force closes the uninstaller. I’ve tried rebooting, other programs will uninstall, just this one shuts it down. Apparently this is a common issue with this program. I absolutely do not recommend installing this!

  3. If you want to keep track of a 5 ton stock portfolio or run a multi-national company this is not your stop. Get back on the bus.

  4. Doesn’t render exactly the same as a mac, but works well enough that I don’t need a dedicated mac computer for testing.

  5. impossible installation, loaded my computer w/unnecessary harmful stuff, even had to spend money on a computer technician — computer still having problems ever since this installation — a disaster

  6. every convert u get a pop up asking to switch to pro version.
    doesnt support hd but i guess what can u expect from free software lol
