Solution

In that location are multiple possible causes for this issue. Following are the most common causes and the appropriate resolutions:

Cause 1

The account used to run discovery is not an Citrix Administrator. Error: "You must be a Citrix Administrator to perform this activity"

Resolution i

Use DSView to check all the Administrators of the subcontract and utilise another Citrix Admin credentials to launch AppCenter.
Once launched, you can change it to any user as per your requirement.

Cause 2

The user is not a member of the Distributed COM Users group on the server:

Resolution two

Add together the user to the Built-IN\Distributed COM Users grouping on the server that you are connecting to. The recommendation is to practise this using nested groups, such equally Citrix Admins group.

Cause 3

The users do not have View Published Applications and Content permissions configured.

Resolution 3

1. In the properties of the Citrix Administrator account, go to the Applications section.

2. Nether the node Published Applications, select View Published Applications and Content (on the Applications node and all sub folders).

   

Cause 4

An application might incorporate an invalid character. (Update AppCenter to newest release prevents invalid characters).

Capture a CDF trace while attempting to launch AppCenter or re-run discovery in AppCenter. Check for bulletin entries similar to:

>Inside GetXmlNodesFromXml
>inside LoadXml
>Exception While Loading XML..srtipping non xml chars and retrying..
>'', hexadecimal value 0x1F, is an invalid character. Line 1, position 2428522.
>Within stripNonValidXMLCharacters
>Failed to call method EnumFarmObjects: Exception has been thrown by the target of an invocation...

If Citrix XenApp half-dozen.v PowerShell SKD is installed a XenApp server, then utilise the PowerShell commands (...
Add together-PSSnapin citrix.*
get-xaapplication | ft displayname, browsername, enabled -auto
...and review the output of the PowerShell command and identify whatsoever awarding that brandish unexpected characters. Example output:

DisplayName BrowserName Enabled
----------- ----------- -------
Excel False
Filezilla v3_▼10 Filezilla v3_▼x Truthful

Note that the Filezilla application includes a unexpected character '▼'.

Resolution 4

Once again if Citrix XenApp half dozen.v PowerShell SKD is installed- Employ the PowerShell command is used to remove the suspect published application.
remove-xaapplication ("Filezilla v3_" + [char]0x001F + "10")

After removing the application, Citrix AppCenter detect works as expected.

Crusade 5

Discovery would fail if a custom administrator has permissions to a nested subfolder just no permissions to the parent folder of that subfolder.

Resolution 5

For discovery to work add atleast the view permission or remove the permissions.

Cause 6

Invalid MFServer entry in database

Resolution 6

In one case object has been deleted, Select "Clean" > "Run".

Cause 7

The business relationship used to run discovery is not an Citrix Ambassador. Mistake: "Yous must be a Citrix Administrator to perform this activity"
