Additional Information:

• What is a FlexNet License Server?
  • The FlexNet License Server refers to the license server program to which most PTC client software connects to request licenses for access to the software. The FlexNet server administers the use of floating licenses configured in its local license.dat file. A PTC Flexnet server can be configured as either a single server or a redundant "Triad" server. 

• What is a floating license?
  • A floating license refers to a licensing scheme where the permission to execute the PTC product is controlled by the FlexNet server (the PTC License Server). In the FlexNet server environment any machine configured as a client will be allowed to use floating licenses until the number of licenses purchased has been exhausted. The license.dat file may be configured with any number of the following 3 floating license types: Licenses-to-run, Floating Options and Startup Extensions.
    The installation of a floating license(s) requires an authorization string, which is specific to the number of licenses (seats) purchased, the expiration date and the PTC_HOSTID for the machine that will run the FlexNet server program. This information is encrypted within the license.dat and any unintentional tampering of this string may cause the floating license to become invalid.
