I just tried on 11.14 target and it works. Probably your version is 32bit or some other defense is also present.

Hi,
Can you send me a link to the full software please? I am not sure that I can help you but can try.

I think that the above errors (using my patcher) relate to this topic: ...

Hi @kronous,
You don't need to use Olly. Just use any Hex editor as such for example Hex Workshop, 010 Editor, etc.

11.13 is the same as 11.11:
4C 89 4C 24 20 44 89 44 24 18 48 89 54 24 10 48 89 4C 24 08 48 81 EC 78

I checked the 11.13.1.0 version.

Here is a simple tool for ECC 11.11-11.13

The patterns for 11.11 are provided here. If I am not wrong:
4C 89 4C 24 20 44 89 44 24 18 48 89 54 24 10 48 89 4C 24 08 48 81 EC 78
Just use any hex editor and find the above sequence and replace...

Hi Darsy,
Yes I can. It seems that this very expensive feature (o.p.l.s 2.1=3) works but I still wonder about this message. The error message is implemented only in the...

Hi friends,
Something interesting :) Last week a new version was released of above discussed target. The defence is the same, no problem at all. However, a new very interesting product has been...

Yes, sure. It is just a simple example but for 11.10 it should work...

Please share when you make solution. It will be interesting for us, thanks in advance!

I made an another FlexLm ECC l_pubkey_verify patcher for the newer versions v.11.10-11.13 (tested on 11.10, 11.11 and 32 bit 11.13). It should work for most of the cases for both Win64/32 and...

Hi carlitos and bilbobaggins,
yes I found that. For me even only patching the .dll file in this way for version 7.7 is ok. I will post the output from the FLEXLM_DIAGNOSTICS=3.

An question for...

bilbobaggins,

This is a great post and very useful guide!! I will try to use it in the current topic too. I don't interest of this software, just trying to help and to learn myself. In fact before...

Hi Jonh,
Thanks for your suggestion! Yesterday I looked exactly into 100c50e0 but didn't know where to place the second patch because the program crash with Segment violation error. You suggest...

@carlitos did you succeed?
If not, probably you should upload your .dll file here and some expert to help. I looked into your files and search how to make check_out function to be patched. However,...

@iceland probably you will give some better direction to @rohank as a starting point..?

Hi dionysosww,
I am trying to find out why I had problems in some cases, and still have, and then will write you. Probably later today.

@synkro I have probably elementary question. Whether the check_signature is always presents or this is only in RSA defence case?
I saw targets, under Linux, that seems to use only ECC protection...

No, it was not present Aleksej. I don't have any other license, only the boot32. However, after patching the check_signature function I added it to the license file and indeed it work. I tested it.

Here something really useful, which I didn't see in other forums!! For the Linux versions 11.10, 11.11 and might be even 11.12 the l_pubkey_verify function in hex is: 41574989FF415641554154554889CD53...

OK, Thanks GEZA!! I will make it asap!

Thanks @darsy! Ok, I wrote PM to GEZA and hope the problem to be solved.

I wanted also to ask you, to avoid any confusions here, if in the cases when l_pubkey_verify is not found whether this...

Hi Darsy,
Yes, I am doing this exactly in your way and used the same software for screen recording as you used, but you can see..The file is 2.12MB, which much smaller than allowed here but it not...

I uploaded the first part of a simple tut here:

Many beginners, like me, initially don't understand neither the sentences even like "patch it to return eax=0" nor the output texts from IDA. For most it is even difficult to work with IDA. I decided...

I made it ;) Thanks to all that give me suggestions in the previous posts and topics. Special thanks to @darsy and @istigatore. I will post a tut.
Now the Linux version is my target..
