About a year and a half ago I wrote a small script to download, decompress, run, and delete restricted files from our company intranet to employee's home computers. I compiled it with perl2exe, and threw it up on the company intranet for people to grab. Now we're finding out that the script doesn't work with Windows 7 and thus needs rewritten. The problem is that the source code seems to have gone missing. This isn't a HUGE problem per say as I've mostly rewritten it from scratch already, but there was a system call in it that contained the encryption key to unlock the files. I need to get that line back. Is there any way to decompile the script or grab the system call while it's running?
