Hi!

I've a little problem:
I'd like to uncompress a self-compiled AHK-Exe-File...

If I use "upx.exe -d Test.exe" the file is uncompressed but ends in "EXE corrupted".

I'm using upx version 2.03..

Compressing and uncompressing after the script has already been compiled is usually problematic. You can, however, remove upx.exe from the compiler directory to have it compile without any compression. [Source]

Thanks jonny!

The topic does help a lot.
But do you know why upx does corrupt the exe when uncompressing or compressing when compiled uncompressed?
Just as Chris mentiones here:

No, I don't know. Sorry.

Hi,


I think I do: It seems the compiler takes the output of UPX and adds something (maybe the script itself?) to the EXE. It you decompress it, you lose that something. The same would happen if you try to compress an uncompressed compiled script (once decompressed in memory, it doesn't find the "something" where it should be in the file).

Thanks, but normally UPX doesn't change anything at the abilities of the exe, but it might be that internal ressources aren't adress correctly..

To decompile a script, you should use "exe2ahk".
You can download it here:
http://www.autohotkey.net/~John/Exe2Ahk.exe

Run it from the command prompt.

He doesn't ask to decompile, but to decompress...

It looks like some sort of bizarre "security feature". UPX doesn't "do" anything, any more than zip or rar does, so it's not UPX's fault. I regularly compress and decompress .exe files from my explorer right-click menus, but AutoHotKey binaries have this "key" of some sort to prevent this.

Why?

It's an Open Source application, isn't it? So why this "feature"?

I'd like to decompress, alter resources (like version info strings, etc) and then compress again, something I do regularly with AutoIt applications.

Is this ever likely to be possible with AutoHotKey?
