Hi,

Since we haven't heard back on this, and we see you have been using the Telerik components after that, I must assume that things are working fine now.

Since our installer cannot tamper with the OS, it needs to rely on some configuration being present in it, and we can't fix that particular scenario. Thus, I have to mark it as "Declined" in order to keep the portal tidy.

Hello Ronald,

These errors could occur when there is no default browser set in Windows. In such a case, Windows Explorer is used to opening the links and they are treated as file locations. Therefore the error that Windows can not find the file.

To determine which is the default browser we check the Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\http\UserChoice. Please check the programId for both the HTTP and the HTTPS and make sure the default program is a browser. On Windows 10 this could be done through Default Apps > Choose default app by protocol. 

If the above is set to a browser, please open this registry Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options and make sure there is not a different program set to launch instead of the browser. For example, if the default application for opening HTTP is Internet Explorer, but in the second registry there is an entry for iexplore.exe with Debugger key set to Windows Explorer, this means that all links will be opened with Windows Explorer despite another program being set as default. Such "debuggers" could be set by anti-virus software as described in this thread.
