Quick citrix tip: Getting “cannot start ” launching app-v app(SMB/Single Admin mode) in XenApp 7.x?

Recently setup a pool of Citrix VDA’s (7.16) to house app-v packages for publication using SMB/Single Admin mode.

On setting up (thought I) followed all the steps outlined in:

but missed a key action on first pass, when launching my app in citrix i would get the “cannot Start <App-name>” message (pretty common and not terribly informational šŸ™‚

Anyways said the key action i did miss was as per above eDoc:

Tip: After you install the App-V client, with Administrator permissions, run the PowerShell Get-AppvClientConfiguration cmdlet, and ensure that EnablePackageScripts is set to 1. If it is not set to 1, run Set-AppvClientConfiguration -EnablePackageScripts $true.

Once implemented was all good to go.



Flexera App Portal tip: how to restrict packages to your native OS

Recently been working with Flexera’s App Portal product and is pretty rich in what it can provide from a functionality perspective eg in particular its leasing capabilities, ability to remove unused applications that users’ have previously requested in particular is an attractive feature as it has the capability to provide a lot of savings to an enterprise from a license perspective.

One issue did come across this week that I wanted to take a mental note of going forward is the ability to only show packages that are native to the OS you are on. Currently undergoing migration to Windows 10 and as part of that are adding more and more applications to the self service portal. As we have a mix of Windows 7 and Windows 10 workstations it was important that packages from one OS weren’t shown as being available when logging on to the other OS (an issue of which I came across this week and which we had such a failure).

So found the fix for this. In order to resolve need to do the following:

i) Log to the admin console of App Portal (normally the URL uses https://<app portal server>/esd/admin

ii) Click on the catalog item which you want amend

iii) Click the Visibility tab

iv) Click the Collections tab

v) Click Add Condition

vi) Choose the particular OS collection you want to limit the visibility and click ok

After that that particular catalog item (or package in self-service terms) will appear from the self-service.


Workspace Environment Management tip: how to enable folder redirection

Recently been getting to grips with WEM as part of a proof of concept and run it through its paces as a possible tool to use as part of a Windows 10 project. Pretty good tool so far must say, installation straightforward enough, interface intuitive – looks like it was built by folks who would use it themselves which is always a good sign.

Does take a little bit of looking around to find some of the settings you might be looking for, for me I want to dump the folder redirection settings had in place in our GPO into it. To enable from within the WEM administration console need to click on (as per below pic):

i) On left hand paneĀ Policies and Profiles

ii) ClickĀ Microsoft USV Settings

iii) Tick the box besideĀ Process User State Virtualization Configuration

From there the options within the 2 Folder Redirection tabs (1/1 and 2/2) will be available so you can start using them for the usual contenders eg desktop/my documents etc




Citrix PVS tip: how to change vDisk assignment for multiple TD’s in 7 easy steps

Oftentimes might face a situation of needing to change your vDisk assignment for your target devices of which there can be many.

In order to do all in one go rather than having to go into each target device and manually modifying each one just carry out the following steps:

1. Logon to your Provisioning Services console, and navigate to your vDisks area and assign the new vDisk to a single target device.
2. Right click the target device and select “Copy device properties”
3. Click the “Clear all” button to de-select all options, then select “vDisk assignment”
4. Click the “Copy” button
5. Select the target devices you want to apply this vDisk to
6. Right click and select “Paste”
7. You will be prompted to confirm these changes and there you are – much quicker than individual assignment changes

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 Ā group policy preference.
