Citrix tip: getting error “Error loading icaconfs.dll” during receiver installation?

Issue – getting error “Error loading icaconfs.dll. The specified procedure could not be found” during installation of receiver 4.3

Seen this occurring sporadically in our environment. Installations would complete but the error would have a knock-on effect –

Users launching apps would see nothing happen. Manually trying to launch .ICA files would have no effect.


Running an SFC scan (sfc /scannow) would show rundll32.dll in the syswow64 folder was missing. If you copied this file from another machine into the folder and re-ran installation issue would go away and you’ll be good.



App-v client tip – unable to run PS scripts without admin privileges?

Just noticed this on the test VDI was working as quite a lot of app-v sequences have dependencies on external powershell scripts.

Noticed on migrating these sequences to Windows 10 had issues with running App-v apps which included sequences that had external powershell scripts that were being called wouldn’t work unless I logged on with a user with administrator privileges. To fix package scripts needs to be enabled.

To enable package scripts you can do one of the following;

powershell command Set-AppvClientConfiguration -EnablePackageScripts 1


change the reg key value to 1 (hex) for HKLM\SOFTWARE\Microsoft\AppV\Client\Scripting\EnablePackageScripts

Needless to say above can add the above key as a  group policy preference.


Citrix tip: Need to relay a maintenance message to your storefront users?

Came across this recently when I had to post up a message to users’ stating some maintenance activity will be occurring over the weekend. Found a tool called Storefront messaging – will see it located near the end of the blog post below

Article is a little old so if you are using Storefront 3.5 definitely need to vet it (mind you, worth vetting if on 3.0 regardless).


Quick and dirty citrix tip: how to hide Desktop Viewer toolbar

Oftentimes be on a screenshare using webex and the desktop toolbar would “get in the way” at the top. As I don’t need it nearly all the time simplest (but it is a dirty method) approach I took to removing was simply to rename its exe CDViewer.exe – located under c:\program files (x86)\citrix

Does the job 🙂




Unable to start app-v client in Windows 10 (build 1603)?

Working on testing app-v packages using Flexera AdminStudio test machine facility (quite nifty actually) and by default was picking up errors using the App-v launcher relating to the app-v client service not being started. Manually starting the service didn’t bring any joy (another error with a -214 code).

Fix for this was simple enough in the end, seems even more than ever powershell needs to be invoked for more and more activities and this is no different. To enable simply go into powershell and type enable-appv like so and it will start up and set the service to automatic and your good to go

Trouble getting rid of them really old citrix receiver versions (6.x / 7.x)?

Came across an issue removing some really old citrix clients (version 7.x) in a locked-down environment that was running (ahem) windows vista machines. Had issues upgrading the receivers on the machines.

As these machines had ICA clients using a version that was packaged using installshield they used an EXE file. The method to remove these files was somewhat different than the later MSI method. To remove successfully:

isuninst –f C:\PROGRA~1\Citrix\ICACLI~1\Uninst.isu –c C:\PROGRA~1\Citrix\ICACLI~1\uninstpn.dll –a.
