I'd also be interested in this issue. A client of ours is currently trying to evaluate how many licenses they need to purchase, a process we (obviously) want to assist with. They are already writing an lmgrd log, but what they need to do is extract license usage statistics or - at the very least - peak license consumption. I think this should be somehow possible without purchasing additional software. @jyadavThanks for your input, but frankly, the article you linked makes my head spin - and I'm a software developer. We'd need a simpler solution than that to assist our client. Thanks Ansgar

Hi all, our Windows software uses the "FlexNet Embedded Client 2019 R2 C XT SDK", the dynamic link libraries FlxCore64.dll and FlxComm64.dll are deployed into the same directory as the main application .exe. This usually works without problems. In rare cases, though, license check initialization fails, and I have found out (through ProcessExplorer), that the reason is that the Flx-DLLs are not loaded at all. I realize that this is not an easy problem to solve, as it happens so sporadically, but have you guys seen anything like it and give me some hints? Here are the details I have: - So far, this occurred on 2 customer machines (different machines, different customers). - On these machines, the effect is reproducable. - However, over machines with the same configuration/software environment/permissions work fine. - Starting the software with admin permissions solves the problem, but is not a permanent solution. - Temporarily deactivating Windows Defender, AntiVirus Software and other "guards" does not help. I thought about maybe linking the Flx dependencies statically, but there does not seem to be such an option: https://community.flexera.com/t5/FlexNet-Embedded-Knowledge-Base/Does-Flexera-offer-static-versions-of-libFlxComm64-and/ta-p/997 Any suggestion would be appreciated. Thanks and regards Ansgar

Hi everyone, the customer has done some great research and was able to solve this problem, but to be frank, I'm not a TLS/SSL expert and I don't fully understand it, so maybe you can help me. I will post the customer's original reply in German, and a translation below. Original reply: ... ich habe die Software und das Lizenzierungssystem jetzt mal mit procmon und wireshark durchleuchtet: Die Software versucht ihre Lizenzierung über einen Webserver auf einer EC2-Instanz vorzunehmen - und zwar per HTTPS (löblich!). Dazu verbindet sie sich in diesem Fall zu ec2-52-49-0-37.eu-west-1.compute.amazonaws.com - das dort abgerufene Zertifikat enthält aber nur die Gültigkeit für die Sites *.flexnetoperations.eu und *.compliance.flexnetoperations.eu. Da das sauber programmiert wurde (sic!) wird damit die Verbindung abgelehnt.... also ich würde behaupten, der Anbieter der Lizenzierungssoftware hat da einen fehlenden CNAME-Eintrag im DNS und sie sollten die Sicherheit ihrer Clienteinstellungen prüfen: So ein Zertifikat sollte eigentlich nicht automatisch akzeptiert werden.... Also die Lösung ist relativ einfach wenn man von Anfang an die Fehlermeldung richtig gelesen hätte: Zertifikat herunterladen und installieren, dann klappt auch die Registrierung, ABER das sollte Flexera in Ordnung bringen 😉 My translation to English: ... I have examined the software and the licensing system using procmon and wireshark: The software tries to fetch license information from a webserver on a EC2 instance - via HTTPS (commendable!). To that end, it connects in this case to ec2-52-49-0-37.eu-west-1.compute.amazonaws.com - but the certificate fetched from there is only valid for the sites *.flexnetoperations.eu and *.compliance.flexnetoperations.eu. Since it was programmed correctly (sic!), this leads to the connection being denied... so I would assume that the licensing software provider has a missing CNAME record in the DNS and they should check the security of their client settings: Such a certificate shouldn't be accepted automatically.... So the solution is rather easy if I had read the error message right from the beginning: Download and install the certificate, then the registration works, BUT Flexera should fix this 😉 As I wrote earlier, I'm not really sure about his suggested fix, and I don't understand how, if this is a general problem, it doesn't cause issues with other clients as well. So any help would be appreciated. Thanks, Ansgar

Hi everyone, I have a customer reporting this problem: ERROR: talking to server: [1,7e3,b,0[74000008,3c,10060221]] Generic communications error. [1,7e3,b,0[75000001,60,3001025c]] General data transfer failure. SSL peer certificate or SSH remote key was not OK I have searched this forum and found this post: https://community.flexera.com/t5/FlexNet-Embedded-Forum/Failing-to-setup-SSL-Communication-within-FNE-C-SDK/m-p/126028 It seems a similar case, but it isn't. This is a cloud FNE server, not a local one, and using the same client software on my own machine, I can activate the same license just fine. So there must something on the client side that's causing this, any pointers as to what it might be? The client tells me Port 443 is open and they even set up an "any" exception to their firewall, they also tested a completely different internet connection (smartphone hotspot), all to no avail. Many thanks, Ansgar

Hi everyone, I have a problem with my email template. I'm currently iterating over my line items and building a table with information, like this: ... [[FOR-EACH TAG="EntitlementLineItem"]] <tr> <td> [[ActivationID]] </td> [[FOR-EACH tag="EntitledProduct"]] <td> [[Name]] </td> <td> [[Count]] </td> [[END FOR-EACH]] <td>[[SeatCount]] </td> <td>[[StartDate]] </td> <td>[[ExpirationDate]] </td> <td>[[LicenseModel]] </td> </tr> [[END FOR-EACH]] ... So far, so good. However, I would like to filter this listing of line items by License Model, and for certain models (identified by name), I'd like to show additional information, like the Instance ID for CLS served items. Now there are several problems with this. While there is a merge tag [[LicenseModel]], it apparently contains composite data; I don't know how to isolate the name from it so I can use it in an [[IF]]. Furthermore, I don't know how to get the Instance ID. There's [[DEFAULT_GLS_INSTANCE_ID]], but it only seems to be working from a global scope, not within my loop. Can you give me some hints how I could solve this?

Hi, this was originally my question, which Eric kindly forwarded here... so thank you, very helpful.
