Just a quick post to let everyone know how to get rid of the annoying problem with Internet Explorer 9 not launching .ica files properly.
Because the regular citrix clients on Citrix.com is not marked as NOT compatible with IE9, some digging was required.
– Uninstall any former Citrix plugins.
– Download new plugin here: https://www.citrix.com/English/ss/downloads/details.asp?downloadId=2313030&productId=186#top
– Install new client and restart browser window.
There you go, user! All better now! 😀
