I wanted to use Firefox with my Citrix Client (ica), but the stupid fuck didn’t install the necessary plug-in files, even a remove/reinstall did not solve the problem..
So I had to install the ica plug-in manually:
Copy those files to FirefoxPlugins:
24’848 cgpcfg.dll
74’000 cgpcore.dll
4’075 ICAClobj.class
45’328 icalogon.dll
319’760 npican.dll
28’944 pscript.dll
69’904 sslsdk_b.dll
24’848 tcppserv.dll
Now create a new subdirectory in the Firefoxplugins directory called Resourceen. Copy those files in the new subdirectory:
33’040 icalogUI.dll
41’232 npicaNUI.dll
28’944 sslsdkUI.dll
Restart Firefox and ica should work now in your Firefox browser!(I used the web client v9.2.5 as source).
Each time I wanted to connect to a Server, the ica Client pop up this error Message:
“The network connection to your application was interrupted, Try to access your application later” .
Each other Workstation was working fine, only my Laptop was the problem.
The Solution:
Under HKEY_LOCAL_MACHINESOFTWAREMicrosoftMSLicensingstore delete the license000 subkey. Now everything works fine!
