CSP Base Licenses not recognised by Studio with XD/XA 7.5 and 7.6

The last couple of months I have been contacted by a few partners and customers were they are experiencing issues with their CSP Base Licenses where the Citrix Studio does not recognise licenses installed on a license server.

On February 10 2015 a hotfix for XenDesktop 7.6.1 was released (CTX141745) that among other things is supposed to fix that Citrix Studio might not recognise Citrix Service Provider licenses and the following error message appears: “Can’t find a valid license”

If you are running an earlier version of XenDesktop you have to use PowerShell (PoSH)  to set the licensing mode.

This is by design and stems from a decision made by Product Management when the XD Advanced mode was added to the product in order to support the CSP Base Licenses. The decision was made not to reflect the availability of that mode within the Citrix Studio GUI and to allow for that mode selection to be via the SDK only.

When you set the licensing mode via PoSH, as described in CTX139752, Studio displays the error that it “Can´t find a valid license” and fails to display any licenses within the Licensing Node.

However, as long as the correct Edition and Model are displayed, users can connect and will actually consume a license from the license server.

Please note: CTX139752 relates directly to XD7.1 – for XA/XD 7.5  the import of the XML (step one on the KB) will not need to be performed. Only the second step, the site- config step, will need to be completed. For example:

Set-ConfigSite ­ProductCode XDT ­ProductEdition ADV ­LicensingModel UserDevice

When initially performing the build of the delivery controllers, using CSP Base Licensed, it is recommended that a temporary 30 day evaluation license be used and upon completion of the build to utilize PoSH and CTX139752 to change mode to Advanced and Per User/Device.

2. Within the Studio Licensing node it reports that it can’t find a valid license and does not display any licenses:

3. Within the Studio Licensing Node, Product Edition screen, no edition is selected, only the Licensing Model:

4. However, a user session can be established and an associated license consumed.
