Okay so whenever i start up horizon (the new version) it flashes horizon has stopped working for a tenth of a second but the other versions work.:help:

Make sure you have Microsoft .NET Framework 3.5

Also try downloading from this link: https://www.horizonmb.com/client/v2/latest.php


You might want to try uninstalling .Net 3.5 and do a fresh install of it.

If you used the .NET Framework tool posted by Gengar did you read the “readme” notepad?


This .NET Framework cleanup tool is designed to automatically perform a set of steps to remove selected versions
of the .NET Framework from a computer. It will remove files, directories, registry keys and values and Windows
Installer product registration information for the .NET Framework. The tool is intended primarily to return your
system to a known (relatively clean) state in case you are encountering .NET Framework installation,
uninstallation, repair or patching errors so that you can try to install again.

There are a couple of very important caveats that you should review before using this tool to remove any version
of the .NET Framework from your system:

  • This tool is designed as a last resort for cases where install, uninstall, repair or patch installation did not
    succeed for unusual reasons. It is not a substitute for the standard uninstall procedure. You should try the
    steps listed in this blog post before using this cleanup tool.

  • This cleanup tool will delete shared files and registry keys used by other versions of the .NET Framework. If
    you run the cleanup tool, you will need to perform a repair/re-install for all other versions of the .NET
    Framework that are on your computer or they will not work correctly afterwards.

…I’m unsure if you could be encountering problems because you have yet to repair/re-install all of the other versions of the .NET Framework, but, like with anything, it’s best to read before doing. Best of luck!
