Automation License Manager (ALM), AuthorsW and Authors handling programs and authorizing and licensing SIMATIC Industry Software

  • Entry
  • Associated product(s)
Here, we provide packed download files with the latest versions of these licensing programs for MS-DOS and Windows.

Authorization of SIMATIC Industry Software requires a red or yellow authorization disk. This disk might include an older version of the Windows handling program AuthorsW or the handling program AUTHORS (MS-DOS) for transferring the authorization. Later software packages install the version V2.4.2 or V2.5.2 of AuthorsW on the hard disk and register it in the system. In this case there is no handling program on the authorization disk.

The new licensing procedure with license keys was introduced in 2003. These keys are supplied on the yellow license disks, on USB sticks or via downloads from the A&D Mall, or are already preinstalled on a Compact Flash Card. The license keys can only be handled with the Automation License Manager (ALM) handling program that is on the associated CD and which is automatically installed by default with the software. More information on license keys is available in Entry ID: 19100818.

Get in touch with Technical Support if your license key or authorization is defective. The Technical Support will support you to restore defective license keys and authorizations. Further informations you will find by entry id: 772175.

Security Note
The Automation License Manager version V5.3 onwards includes important security improvements. If you have version of ALM previous to V5.3, we recommend installing this update immediately. This update is compatible with all ALM V4.0 versions and higher. The above-mentioned operating systems are supported by the Automation License Manager in order of their product release.

Upgrading of the operating system is not supported. More information is available in the ALM readme file. Proceed as follows to install.

  1. Click the "114358_ALM_V5_3_SP3_Upd3.zip" link to open the packed file.
  2. Unpack the file in a separate directory on your hard disk.
  3. Close all the programs before starting the Setup.
  4. Start the "Setup.exe" in your directory.
  5. Follow the instructions of the installation program.

A check is made automatically before the installation as to whether your operating system is compatible. Then the version of ALM relevant for your operating system is installed (32-bit or 64-bit). You can also start one of the lower-level installation programs in the "ALM32" or "ALM64" folder. Example:

  • for Windows 7 (32-bit) the "Setup.exe" in the "ALM32" folder
  • for Windows 7 (64-bit) the "Setup.exe" in the "ALM64" folder
