Extracting file from MSI package

[new_profile]

You're right. I've found that any expired key will be accepted with no problem.
I've played a little bit with the server.jar and FileChunk class and it seems that even the JD-GUI doesn't decompile it.
Back to java disassembly to see what to do with.

Thank you

Or just use msiexec command line like :

msiexec /a youMSIfile.msi TARGETDIR="Path:\\where\You\Want\The\File"

This will do an administrative install, you should then get the files with the all Folder tree from inside the msi
