HowTo - Handle 'Invalid License key' error in BioManager

BioManager reports error “Invalid License Key” after applying the license key.


Solution

In few installations, we observed that this error is caused by local Windows IIS server rejecting the 'PUT' REST call which is invoked when the license is applied in BioManager. 


Pls verify the following resolution items in given order:

(1) In particular, the IIS feature 'WebDAV Publishing' could block the PUT call. This feature is usually intended only for software development machines and not for test or production servers.  
If you don’t need to use WebDAV, then the simplest solution is to remove WebDAV from your system. It can be performed in "Turn Windows Features On or Off" by unticking the checkbox as shown in below snapshot.
After removing the feature, restart the server machine for the changes to take effect.



(2) Verify that under IIS settings for TBS website, the option "Allow unlisted verbs" is enabled under Request Filtering - Edit Feature Settings. 
 

(3) If the 'PUT' call is restricted in the general server settings, then 'PUT' verb has to be allowed for TBS website under Request Filtering - Edit Feature Settings - HTTP Verbs - Allow Verb as shown below:


In case error persists, ensure that the License Key matches with Installation / License ID.
