i have a file packed with telock , i have UNpacked it with two ways.
1- manually , olly ( dump )
2- by using unTelock.

the unpacked file doesnt run if the original one (packed) is not running.
i should run the packed file 1st , then the unpacked file <-- will work.

but if i run the unpacked file it will close after 1 second.

what is going on?

hint: have a look at the telock options

...or search this board... I think I remember what this is... createmutexa...

i dont know , but i see no much threads! , i opened packing/unpacking section
it has 4 threads only
Showing threads 1 to 4 of 4 , is there a problem ? or its only has 4 threads?

Manko , what to search? there is nothing lol!

Change your board settings...there are more than 4 threads...

yes, it is the option "mutex" which is surely used as Manko said. The TElock loader creates a mutex and the target test if this mutex exists. If you unpack the file, the loader don't create it and the file unpacked kick you out you just have to break on createmutex... you must find something like this :

call CreateMutex
call GetLastError
cmp eax, ERROR_ALREADY_EXISTS
jnz Get_Out_Of_Here_If_You_Are_Lucky (it could be a devil routine !! )

also sometimes prog can do some check.. check that name of general exe not changed, not sure but maybe this trick can be exist here..
