View Full Version : flexlm

Firstly, this is my first post and forgive me if I didn't post in the right place.

Secondly, I have an application using FlexLM and after reading some tutorials and papers, they say to download the FlexLM Programming KIT in order to use the keys and the encription seeds.

So, where I can find this kit?

I wasn't!

Now returning on topic and leaving the joke aside:

The application I'm talking about is using lmgr3627b.dll so this means it's using FlexLM 7.2.

Now, what I need to do after getting the keys and seeds?

after getting the keys and seeds you need generate license.

Usually, that's the right path, but it doesn't work.


#define VENDOR_KEY1 0xdeadbeef
#define VENDOR_KEY2 0xdeadbeef
#define VENDOR_KEY3 0xdeadbeef
#define VENDOR_KEY4 0xdeadbeef
#define VENDOR_KEY5 0xdeadbeef
#define CRO_KEY1 0xdeadbeef
#define CRO_KEY2 0xdeadbeef

#define VENDOR_NAME "deadbeef"

An error occured while initialising FLEXlm. Invalid FlexLm key data supplied. In file .\lm_code.h

Did you use the "calcseed" utility to recover the seeds?

Maybe I'm still missing something. Back to the drawing board and a lot of stepping

So this is how you find out VENDOR_NAME and the 4 keys. Now only key4 and both of seeds.


Then, why to use "calcseed" utility for? What does it do and it's version specific?

I didn't know AOL was protecting its software now days w/ flex;

Jokes aisde, if you're really working with 7.2 - there is more than enough info around here to get you all you'll ever need.

Have a look at Nolan Blender's "Zendec" tutorial.

November 12th, 2013, 16:44
Yeah, there is enough info here.

About that tutorial, it shows how to recover the seeds and keys. I think I still need the specific v7.2 sdk in order to generate the password. Or I can use other version easier to find?

And from the reversing point, I got the difference between recovering keys for v5 and v7.

Probably easiest to look for and use the "lmcryptgui" utility to generate your license once the seeds have been recovered.

Doubt it'll help you but for generating the lics, this is what I ended up doing:
