After upgrading NetScaler to 13.1 build 64.39, the GUI loads normally, but I’m unable to click or open any of the tabs/options in system upgrade option.

Does anybody know if this is normal? I only use Citrix for a single program (Powerchart). A single file called "SettingsInterface.log" in AppDate is taking up 50GB+ of space. I can't find information about this file anywhere.

I use citrix for work (accessed on a personal Windows laptop).
Everything was working fine yesterday, and suddenly today when I try to open my .ica files, Citrix won't load and generates this pop-up.
Command prompts, searches, etc. cannot locate a "Desktop Lock" file anywhere to uninstall.
Tried uninstalling and reinstalling the whole program but same issue.

Anyone ever had this happen and how do you resolve this?

New Patch and a lot of new CVEs..happy friday.

Hello,

After installing the November updates on my ServerOS VDA (Server 2022), the following error appears in Studio during deployment: Image preparation failed to rearm the copy of Windows installed on the master image.

The deployment still completes successfully for me. On the updated VDAs, I see four entries in the event log that must originate from the preparation VM.

3 copies of this event entry—one for each Office product (Office, Visio, Project)

The control module reported an error during VL activation.

Cause: 0x8007267C

AppId = 0ff1ce15-a989-479d-af46-f275c6370663, SkuId = 8d368fc1-9470-4be2-8d66-90e836cbb051

Trigger=TimerEvent

And this entry (Windows activation)

Error during license activation (slui.exe). Error code:

hr=0x8007139F

Command-line arguments:

RuleId=eeba1977-569e-4571-b639-7623d8bfecc0; Action=AutoActivate;AppId=55c92734-d682-4d71-983e-d6ec3f16059f;SkuId=9bd77860-9b31-4b7b-96ad-2564017315bf;NotificationInterval=1440;Trigger=TimerEvent

Both Windows and Office are activated on the updated VDAs. I don't see any errors or anything like that.

Microsoft has already listed this issue under “Known Issues”: https://support.microsoft.com/en-us/servicing/os/windows-server/2026/11/kb5131090-windows-server-2022-security-update

Slmgr doesn't seem to be working properly, which explains the message in Studio. You can't launch it manually either; an error appears there.

I'm not sure—can I roll out the update now or not? How do you guys handle this?

Thanks!

Anyone else run into this problem?

Got reboots scheduled in Citrix Studio, but for some reason random VM's will shutdown instead of rebooting.

VM's are running in vSphere.

Hey everyone,

Every month after Patch Tuesday, we run into an issue with a couple of our Azure-hosted VDIs getting stuck on a BSOD or a black screen with an error.

Right now, our workaround to fix it is:

1. Detach the OS disk from the broken VDI and mount it as a data disk on a healthy VDI.

2. Bring the disk online and wait a bit.

3. Reattach the OS disk back to the original VDI.

100% of the time, once we boot it back up, we see Windows Update finish its installation and the machine recovers.

Because of this, we strongly suspect that Citrix Autoscale is powering down or deallocating the VDIs right in the middle of a Windows Update reboot/installation, corrupting the update state.

Has anyone else run into this exact behavior with Citrix Autoscale and Azure VDIs? If so, how did you solve it (e.g., maintenance windows, draining machines before patching, tweaking Autoscale schedules)?

Any advice would be appreciated!

Hello, everyone, I hope all is well. I had upgraded my Windows 10 Citrix PVS single session VDIs to Windows 11. Testing has been fine but user mentioned some slowness between switching their clinical apps. I read Windows 11 is a little bit bulkier so I’m not sure if I need to adjust my sizing. The specs below are what our Windows 10 devices have always used. Except for the page file. Win10 had that set to system managed and decided to restrict to 2048 after being suggested it’s bad practice to not have a value statically set. What do yall have set for Win11? What do you suggest? My main concern is ensuring our write cache drive doesn’t fill up and cause crashes like we experienced in the past

Hypervisor: VMWare
CPUs: 4
RAM: 10 GB (I’m aware about the 4-1 ratio. This wasn’t my decision. Company trying to manage resources)
Write Cache Drive: 25 GB
Pagefile: 2048 MB
VDisk is set to Cache in device RAM with overflow on hard disk and Maximum RAM size (MBs) is set to 64.

I have been using Citrix Workspace app for a long time and for some reason I had to uninstall it (used Revo Uninstaller). When I try to install again (Latest v26.10.0.31), no install progress and it fails with Installation error (Picture A).

Then I tried an older version 26.3.20.9, it installs but never opens. Also, no luck when I try to open from start menu shortcut. I looked at the event log (Windows>Application) and found below errors each and every time I start Citrix Workspace app. I tried so many steps and many commands (>CitrixWorkspaceApp_x64.exe /CleanInstall, >CitrixWorkspaceApp_x64.exe /ForceInstall) but still I am unable to figure out what is causing this. So, I am looking for someone's assistance to get this resolved.

Thank you in advance.

Does this mean we are going to have monthly patching for Netscaler now and we will need to patch this Thursday, Nov 12?

It is in my personal computer, I don't know how or why Citrix is in it. I don't have a log in to download the removal tool. Mainly, I need to get rid of ctxusbm.sys. Thank you

Hello,

I am trying to consolidate a vdisk from 10 or more versions down to 2-3. I want to merge them but still retain the current prod version and the most recent two - is this possible? From what I can tell in the docs and the UI it just merges everything.

I know that Citrix have been re-jigging their certifications, but I’m at a loss to find any information out at all at this point. Their website’s training and certification section goes over how there are three levels and three tracks - Associate, Professional and Expert levels, in either EUC, NetScaler or Security. All good, but it gives absolutely no information at all about requirements, what sort of things are covered, and the training materials is simply links to external company websites. There used to be a ton of study materials available.

If you click on the link to ‘explore certification exams’ it takes you to a company called Web Assessor, and from there you can register for EUC exams but again it tells you absolutely nothing about what you need to study.

If you click on the links to in-person training, then depending on country it offers three more links to QA, GlobalKnowledge etc - all of whom are only offering courses named for the old tracks of CCA-V, CCP-V and CCE-V.

Am I just missing something, or is it still just as much of a hot mess as it was six months ago? I got my CCE-V three years ago and need to think about re-certifying, but it seems they are struggling to put something sensible together. Or, are they just not going to bother, since the product as a whole is basically fading away anyway?

Hello,

My organization is replacing our old 4 x V570F (basically just a R740XD) VxRail vSAN cluster and will continue running vSphere/vSAN file services/Horizon on new hardware. I administer/manage/audit the on-prem VDI environment and the vSAN cluster (phew!). Management has approved me using the old VxRail hosts to evaluate alternative hypervisors + VDI solutions and I have landed on XenServer/DaaS+MCS as the "Horizon instant clone equivalent". My question is, for your environments, how do you provide HA storage to the VM's running on the hosts? The most simple solution in my head is a NFS share on a Debian/Ubuntu VM, but its the "HA" component where I am lost and looking for more information (windows server failover clustering maybe?)

I have also read Starwind is another potential storage provider, but I am new to this and reading a lot of posts they seem to contradict each other. I am looking for something a bit more bulletproof and resilient than 3rd party science experiments like Ceph (kind of joking). Any advice/documentation would be incredibly useful.

Thank you!

Hi everyone. I was just switched from Omnissa Horizon to Citrix Workspace today. On Horizon, ctrl+alt takes the desktop out of focus. So a command like "ctrl + alt", followed by "alt+tab" brings up the Tab Switcher of my Host Desktop, and I can navigate my host desktop.

I understand Citrix Workspace has a feature like this with ctrl+alt+break, maybe. There's two problems. 1) It brings up the tab switcher, but it doesn't actually navigate away from the Citrix Desktop. I can switch to anything I want, my view never changes. 2) This requires two hands, and I'd rather not have the Break key involved.

Am I doing something wrong? Is this just how it works? There don't seem to be many settings but is there something I can change to correct this?

Thank you!

We currently purchase many SSL certificates from DigiCert for applications “hosted” on on-premise NetScaler. The certs are reissued and manually installed on NetScaler every 199 days. There have been discussions that DigiCert will reduce the validity period to 47 days. Can the certs on NetScaler be auto renewed? Are there any inexpensive CAs (options) that support auto renewal?

I’m setting up a parallel Citrix infrastructure with CVAD 2507 CU2 and have run into an issue where the Delivery Controllers are unable to connect to the newly restored databases. I also tried running the database scripts against the newly created empty databases, but I’m still encountering the same connectivity issue. Has anyone experienced something similar or have any suggestions on how to troubleshoot and resolve this?

Has anyone else noticed any issues with the Citrix website?

All of a sudden, all of our admin/accounts that are linked to email addresses (not the old web logins) are getting access denied when trying to access any downloads, we all get the same embargo country error - but we can still access case management and live chat.

Citrix seem to have no idea why and won't tell us what has changed when it's locked all of us out. So if there is a NetScaler patch or something else over the weekend, we're doomed.

We can't even get into the "My Account" page because of the same Embargo error, regardless of whether we're in the UK, US or anywhere else. This stinks of Citrix making a change or breaking something.

Thanks

Citrix suggested to upgrade to 2607 as this 2603 has some bug which is preventing users to launch app.

Edit:- Issue was due to some cert got removed from MS during patching which caused issue with 2603. And solution was to upgrade to 2607

Anybody updated their on prem netscalers with this fix version? I read another post saying they had issues. Just wondering if anyone has ran it and if they saw any issues?
