Citrix FTA, URL VDA redirector

You might see this message when users are opening internet Explorer on your XenApp servers.

A website wants to open web content using this program on your computer.


One way around this message is to create this registry settings for every user.


Settings as a reg file:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Low Rights\ElevationPolicy\{DB5C2E14-897C-4AE8-B798-E77136187F5E}]
"AppPath"="C:\\Program Files (x86)\\Citrix\\system32"

You can for example set this by a login script or a Group policy preference.

By using these keys the prompt will not show up. This is just one way to remove the prompt.
