Frequently Asked Questions


Q. Which licenses should I update to REV11 licensing?
A. If a license meets all three of the following criteria, you’ll need to update it to REV11 licensing before the license’s renewal date in 2021:
  • It’s on a currently-supported Windows or Unix system AND
  • It’s using a Synergy/DE version between 9.5.3b and 10.3.3 AND
  • It’s a subscription license

We also recommend that you update traditional (non-subscription) licenses to REV11 licensing (9.5.3b – 10.3.3, Windows and Unix).

See our platforms page for information about currently-supported platforms. If the current Synergy/DE release is not supported on your platform (e.g., your specific O/S version), then REV11 licensing is also not supported there. For example, Windows 8 and Windows Server 2012 are the lowest Windows versions supported by REV11 licensing.

Q. When should I update my licenses to REV11 licensing?
A. We recommend you update each license to REV11 licensing before the license’s renewal month so that your product keys can be automatically updated when Synergex processes your renewal. So for example, if you have a license that renews in June, we recommend you update it before the end of May.
Q. Will I still be able to get product keys for licenses using Synergy/DE versions lower than 9.5.3b?
A. Yes, Synergex will still provide “pre-REV11” keys for lower Synergy/DE versions.
Q. Does REV11 licensing work with Synergy/DE versions lower than 9.5.3b?

REV11 licensing is supported and required for Synergy/DE 9.5.3b and higher. It should not be used on production systems with any version lower than 9.5.3b due to a runtime issue in older Synergy/DE 9 versions.

Some Synergex customers are using REV11 licensing on development systems with Synergy/DE 9.3.1-9.5.3a. It can be used on these systems, but you should be aware of the runtime issue that could occur: if License Manager on your system updates keys while a Synergy application is running, and if the application is not stopped and restarted, after a period of time (dependent on how much the application is being used), the application could crash. Since Synergy applications are started and stopped frequently on typical development systems, and there typically aren’t many application users, we don’t expect this issue to occur on development systems.

On systems with Synergy/DE versions lower than 9.5.3b,

  • If you have REV11 licensing on a production system (i.e., a system running business operations), or any system running Synergy applications for long periods, you should upgrade to 9.5.3b or higher, or remove REV11 licensing and revert to Synergex’s previous licensing system.
  • If you have REV11 licensing on a development system (where Synergy applications are started and stopped frequently and they don’t have many users), out of an abundance of caution, we recommend that you update to 9.5.3b or remove REV11 licensing. That said, we don’t think you will encounter the issue on these systems.

If you want to remove REV11 licensing from a system with a version lower than 9.5.3b, contact Synergex Developer Support. They will provide a “kill string” and instructions for uninstalling. After you update your system to pre-REV11 licensing, send the new registration string and Licensee name to Customer Service who will provide you with new keys.

Q. If my system loses connection with the Synergy License Web Service, will my application to stop working?
A. No. Your license server only connects to the Synergy License Web Service periodically to check for new keys (typically once/week). Once you have REV11 licensing set up and product keys installed, loss of connection to the Web Service would not cause your application to stop working. If there is an issue and your license server can’t connect when it’s time to poll, you and Synergex will be notified via emails and logs. The keys installed on your license server will not be affected, and your application will continue to run normally.
Q. What should I do before I update to REV11 licensing?
  1. Check the OS requirements for your system. The licensing upgrade package is available on platforms supported by the current version of Synergy/DE.
  2. Run the lmcheck utility to test your system’s connectivity with the Synergy License Web Service and verify your license in Synergex’s database. You can download lmcheck from the downloads area in the Synergex Resource Center.
  3. Read and follow the “Before you install…” instructions for using the REV11 licensing upgrade package on Windows or Unix.
  4. If your applications use the SERIAL routine (which returns the registration string), you’ll need to make some changes to accommodate the longer string used by REV11 licensing. First, do a case-insensitive search of your source code for “serial”, and look for instances of “xcall SERIAL” (in case there are tabs, spaces, or returns between the words). Then refer to Synergy KB #2467 for details on what to do.
  5. If you use Licensing Toolkit, see the question below.
Q. How does REV11 licensing affect applications that use Synergy/DE Licensing Toolkit?
A. If you use Licensing Toolkit (which enables you to build Synergy License Manager license enforcement into your applications), before you update to REV11 licensing, you’ll need to:
– Get the latest v11 Synergy/DE Licensing Toolkit from Synergex Customer Service.
– Use this version’s License Key Generator (lmk.exe) to generate keys. It can create REV11 and pre-REV11 product keys, depending on which registration string is passed to it.
– If your code uses the LM_INFO routine, or if you’ve written any code that uses the registration key or product key, update your code to handle the larger sizes of these fields.
– If you generate keys individually to the screen, or if you generate keys to multiple .skf files for a single machine, or if you concatenate .skf files, change your process to instead generate all keys for the system to a single .skf file.
– If you’re using a version 11 License Key Generator prior to 11.1.1d, and you use a producer file, remove the producer files from your client and server machines.
Q. Will we be able to manage our Synergy/DE licenses in the Licenses area of the Synergex Resource Center?
A. Yes, we encourage you to use the Licenses site to manage your licenses. You can view details for all the licenses for your company, including the license number, licensee name, OS, registration string, products, and polling data. You can also generate install codes when installing REV11 licensing on new systems. Note that you cannot generate product keys for licenses that use REV11 licensing as those keys are automatically downloaded from the Synergy License Web Server. We recommend that you have one or more Site Admins (employees with permissions) who are familiar with this site. Contact Synergex Customer Service to add Site Admins. Also note that your Site Admins can control who from your company can access your product licenses on the site.
Q. How can I get access to the Synergex Resource Center or to a specific section of the Resource Center (e.g., Downloads or Licenses)?
A. If you don’t already have a Synergex Resource Center account, go to the Resource Center, and click “Create Account” in the top right corner of the page. If you don’t have permission to access a specific page on the site, contact your company’s Resource Center Site Admin or Synergex Customer Service.
Q. I’m not upgrading my license to Synergy/DE version 11-why do I need to update to REV11 licensing?
A. REV11 licensing is not only for Synergy/DE version 11. It’s also for Synergy/DE versions 9.5.3b – 10.3.3. It’s important for licenses to move to the current licensing system. Synergex requires REV11 licensing with DevPartner (development) licenses and subscription licenses on Windows and Unix.
