This installation code is a very good criteria if you need a company wide (unlimited) license with single user installations.
After a user logs in his Windows account, the Windows-Domain name is used for copy protection. This also works for notebook users which are offline, as you can always log in using the domain-name.
There are 2 options
• The same license file can be copied to any machine. No additional activation is necessary after the first user has activated the product
•The same Serial Number can be used within the domain for multiple product activations (see settings for Activation Server below). There are no restrictions, how often the Serial Number can be used.
To allow a reactivation, you have to limit the reactivation exclusively to the domain. These are the settings for the project.config file
<InstCodeType1>12</InstCodeType1>
<InstCodeType2>5</InstCodeType2> (this would be used if the network works without a domain)
<InstCodeType3>1</InstCodeType3>
<AllowReactivation>Yes</AllowReactivation>
<CheckInstCodeType1>12</CheckInstCodeType1>
<IgnoreLocalInstCodes>false</IgnoreLocalInstCodes> (definition is mandatory for reactivation using domain)
<MinIdenticalInstcodes>12</MinIdenticalInstcodes> (backup ID if no domain is available - then no reactivation is done as 12 IDs have to match)
Every workstation has to specify the same domain for login like domainname\username
This ID can only be used as a single PC / single user license. A network license is not supported.
This feature is only available in the Professional Edition.
