How do I allow to make a reinstallation on the same machine?

It is possible to allow by default, that a user can install the application multiple times on the same PC.

Scenario

•	Customer installs and activates the licence

•	Customer uninstalls the application

•	Customer reinstalls the application

By default, the reinstallation would not work, because it is counted as a second activation.

To recognize a PC, hardware ID’s are compared with former activations and only if hardware ID’s match, the module can be activated again.

A PC is considered identical if at least the number of installation codes, defined with MinIdenticalInstcodes, is identical – e.g. MinIdenticalInstcodes = 3 would need at least 3 identical installation codes out of all available codes (version 2.4 there are 9 codes) to be identified as the same PC.

MinIdenticalInstcodes is ignored if a list of installation codes is defined with CheckInstCodeType.

Example:

(installation code number 5 ensures that the version can not be installed again on another directory). A missing code 2 and 6 would allow an installation after a new network adapter was installed.

Depending on this definition, the Web Activation Server will compare only those 3 Instcodes to determine if a PC is identical.

•	To turn on this feature - see AllowReactivation

•	Set the values how to identify a machine - see MinIdenticalInstcodes

•	See also CheckInstCodeType and IgnoreLocalInstCode for additional configuration options

If this feature is turned off, the maximum number of tries have to be incremented by 1 manually - see Modify an Activation

To use this functionality with EasyGo you have to generate a Serial Number with the option Unlimited Installation. <%MME%> creates all keys with this option turned on.
