Need some advice to analyze dll

[vlkc_user]

Hello, from site warelogic dot com I've downloaded tool which is not packed and not protected with any protector. I can not find how with ollydbg take out 60 days limit.

I also sow that in registry - setup always creates new key. And I think for another 60 days

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Warelogic\SimpleLPR2]
"License"=hex:58,13,cf,0a,72,cd,e4,40,6e,2f,6a,30,e0,cf,24,8e,4e,d4,87,9a,44,\
  62,d6,23,70,17,09,d9

If I delete it and install again then software works again. Maybe I have to decompile installer?


Anyway - please advice where to go

Thank you.

bro open the application with ollydbg and it should load the that dll. Analyze it and find the functions that are imported from that dll by application. that's it..

I have tried, but no luck. Can you help me?

This is a net program, in that case OllyDBG is not useful to debug the software.

Use a .Net debugging/Reversing tool like Reflector (do a search and you can find patched versions very easily) or DnSpy for example, as Olly is not very efficient for .Net programs.

You can use Ida Pro for a prelim anaysis first...
