Citrix Apps Won't Launch in Windows 8 or 10

Windows 8 and Windows 10 both sometimes set IE or Edge browser as the default program for opening citrix apps. These apps need to be opened by Citrix Receiver in order to work.

Issue / Question

Sometimes in Windows 8/8.1/10, Citrix Receiver does not get set as the default program for opening *.ica files.

Resolution

1. Right click an ica file on the local hard drive and select Open With -> Choose Another App
2. Select "More Apps", and then click "look for another app on this PC" even if you see citrix receiver in the list
3. Navigate to C:\Program Files (x86)\Citrix\ICA Client
4. Look for wfcrun32.exe and select it then click OK.
5. Check the box "Always use this app to open .ica files"
