How-To-Config

.ica won’t open in Internet Explorer

It took me a while to find the resolution for this problem, although alot of users seem to have this problem. Finally I found how to resolve this issue once and for all:

In Internet Explorer go to:
Settings -> Internet Options -> Security Tab -> Trusted sites -> Sites
trustedsites

In the Trusted Sites window add your Citrix web URL. Both http & https:
addtrustedsites
Apply the new settings, restart Internet Explorer and the .ica files will automaticlly be opened with Citrix Receiver.

    THank you,

    My IE will now allow me to open ICA files-is there anyway to get google chrome to work

  2. FeelPlanet says:

    The issue occurs because Internet Explorer or other browser cannot access or trust the cached ICA file.

    THANK YOU!!! I have been researching, uninstalling/reinstalling citrix receiver, looking for answers for days! So simple and easy, but I just didn’t know where to look. Thank you thank you!

    The fix is to associate .ica files to wfcrun32.exe in the C:\Program Files (x86)\Citrix\ICA Client folder (trust me on this) Both Chrome and IE will launch the .ica without prompting afterwards

          after the Launch.ica is downloaded, don’t open it, instead, open the folder that it’s downloaded to.
          1) right click on the launch.ica file,
          2) choose “open with”
          3) a window should pop up, depending on the version of your windows it may look different but look for an option to “choose other programs”
          4) once you found that it’ll ask you which program to use,
          5) navigate to the wcfrun32.exe file that other have posted above.
          6) hit OK and open. Voila.
