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.

Fix

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.

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

https://www.citrix.com/blogs/2015/07/15/storefront-3-0-message-customization/

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 🙂

 

 

 

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.

 

Troubleshooting HTML5 receiver issues

Recently in the lab updated the HTML5 receiver (version 2.3) on my storefront servers. After which hit issues with my connection going “in and out”.

Turns out my patching wasn’t up to scratch. XenApp 6.5 environment and moving hotfix rollup pack 7 (per CTX129229) resolved the issue.

What was instructive was enabling HTML5 logging per https://support.citrix.com/article/CTX217352

What did help me gather from it was it was session reliability-related. Sure enough when I switched it off all worked. Ultimately though did want to leave enabled so updating to latest HRP resolved but the HTML5 logging was very useful on this occasion as reasonably negligible so a good takeway

 

Citrix PVS tip: how to install PVS powershell snap-in

Recently was looking to utilize the vDisk replicator utility (see: https://www.citrix.com/blogs/2017/04/12/vdisk-replicator-tool/) which had a requirement for the PVS powershell snap-in. After a few times did manage to get the snap-in to work but have to be careful to get the syntax correct which was in the end:

C:\Program Files\Citrix\Provisioning Services Console>C:\Windows\Microsoft.NET\Framework64\v4.0.30319\installutil.exe Citrix.PVS.SnapIn.dll

After that was up and running with my replicator
