How to Determine Which erwin Licenses are Installed (applies to r8 and later releases) (4292369)

 Description

It is often desirable to inventory several workstations to determine what software is installed and licensed.  The functionality available in erwin Data Modeler releases r8 and later is controlled though the license (or licenses) installed on the system, so examining the license files will provide information for all licensed versions of  erwin Data Modeler r8 or later.

NOTE: This information applies to stand-alone local machine licenses.  It does not apply to concurrent licenses for use with the erwin license server.

Location of erwin License Files

Before we examine  erwin license files, we must first know where to look for them.  Here are the folders where erwin licenses may be saved.

• Releases r8.1 and earlier*
• Windows XP:
• C:\Documents and Settings\LogonId\Local Settings\Application Data\CA\erwin Data Modeler\8
• Windows 7:
• C:\Users\LogonId\Local Settings\Application Data\CA\erwin Data Modeler\8

*NOTE: For release r8.0, the name of the final folder is “…\8.0”

• Releases r8.2 and later r8.x
• Windows XP:
• C:\Documents and Settings\AllUsers\Application Data\CA\erwin Data Modeler\8
• Windows 7:
• C:\ProgramData\CA\erwin Data Modeler\8
• Release 9
• Windows XP:
• C:\Documents and Settings\AllUsers\Application Data\CA\erwin Data Modeler\9
• Windows 7:
• C:\ProgramData\CA\erwin Data Modeler\9

Licenses that are not installed to one of these folders will not be recognized.

NOTES:

• If the root folder is not “C:\”, please alter the above paths accordingly
• Some folders can be aliased, for example on Windows 7 “C:\ProgramData” and “C:\Users\AllUsers” are equivalent and point to the same location.

erwin License File Names

CA erwin license files will always have an extension of “.lic”.  In fact, any file in the license folder whose extension is “.lic” will be treated as a potential license file and scanned for valid licensing information.

An erwin license file is usually named to indicate the type of license it represents.  MAC-based licenses usually include the MAC address in the filename.  However, since any file with an extension of “.lic” is treated as a license file, the filename cannot be relied upon to provide definitive information as to the type of license it represents.  For this, it is necessary to examine the content of the file.

Anatomy of an erwin License File

CA erwin license files are plain text and may be viewed using any text editor (such as Word Pad or Notepad).  Editing an erwin license file will render it invalid, so please be sure not to save any license file after viewing it in a text editor.

The above example is for a MAC-based license for erwin Data Modeler r8.x Standard Edition and it has an expiration date of December 13^th 2013.  It was generated on January 1^st, 2012 and issued to a company named "My Company, INC." whose SiteId is : "1234".

The first line contains the date and time for when the license was generated. 

The first “FEATURE” line (line 2 in the above example) has the name of the application (“erwinDM”) followed by “erwinmod”.  The next element is a numeric value representing the version of erwin Data Modeler being licensed.  For erwin DM r8, that value will be “1.000” or it may be a number beginning with "8." ; for erwin r9 it will be “9.000”.

The version is followed by a date indicating when the license will expire.  If the word "Permanent" appears there, the license has no expiration date.

The next item of interest is the value for “HOSTID”.  For MAC-based licenses, the HOSTID should be the MAC address for the machine.  

Finally, the value for “user_info” is the company name followed by the Site ID for that company.

IMPORTANT: For users of the erwin Data Modeler Workgroup Edition, It is very important that the company name in all licenses have precisely the same company name—including capitalization, spaces and punctuation.  If the company names do not match exactly, the license will not permit connection to the Model Manager mart.

The second FEATURE line is like the first, except that the second element indicates the “edition” of erwin Data Modeler.  In the above example, the value is “Standard” indicating that the license is for erwin Data Modeler Standard Edition.  That value may be either of the following:
