When CA ERwin Data Modeler r7.3 is launched if no license is detected, the option to enter a RegIT Key to create a new license is presented. In some systems, particularly Vista and Windows 7, the process does not complete successfully.
IMPORTANT: This article contains information about modifying the registry.
Before you modify the registry, make sure to create a backup of the registry and ensure that you understand how to restore the registry if a problem may occur. For more information about how to backup, restore, edit the registry, please review the relevant Microsoft Knowledge Base articles on support.microsoft.com.
When licensing CA ERwin r7 applications, a license file named “ca.olf” is created. This file is located in a folder named “CA_LIC” usually at the following path:
(the CA_LIC folder can sometimes be at the root: “C:\CA_LIC”)
Under Vista and Windows 7, these folders have restricted access and are usually read-only. If the folders are read-only, when the CA Licensing process attempts to create the license file, an error is generated and the file is not created. This can be confirmed by looking in the CA_LIC folder for a file named “ca.olf”. If the file was not created it is most-probably due to permissions.
The solution is to logon as a user who has full read-write access to the CA_LIC folder and then license ERwin. After ERwin has been licensed normal privileges may be restored.
If, when attempting to license ERwin r7, the 25-character key is identified as already in use, you can reset that key by using RegEdit to rename the following key:
After renaming the key (to something like “…\Products_old”) you will be able to use the RegIT key to license ERwin.
If this process presents a problem, please contact CA Support and reference this KD. The support engineer will be able to create a license file for you. You will then need to copy the “ca.olf” file to your CA_LIC folder.
NOTE: This same behavior can occur with Windows XP if write access is not available under the "CA_LIC" folder.
