1. The program contains 1 exe file and 1 dll file.
exe file is packed by 1 packer.
dll file is packed by another packer.

If we only unpack the exe file, will the program still run well ?.
If not, in this situation, how should we do.?

2. I do not know the keyword to "google" this situation, tell me plz.

With the only exe unpacked, the programm should run, otherwise there's a Checksum control into the exe or into the packed dll.
Only the debug can give you the answer

check the unpacked exe file with pe ID 0.94.
I saw that : " Microsoft Visual C++ v7.1 EXE * "
I am wondering :
what does star (*) mean ?

Good question, what does this star mean ?
I just saw that it put a star on every files i give to analyze.

Start * indicate that the signature of file was determined from userdb.txt, not from internal signature database of PEiD.

Thanks, now i know.

if you unpacked the exe only,it can run well

but the kew words...sr...I don't know too...
