In order to test my Tcl script, I had to write another one to "break" the files. :blink: As reported earlier, only certain generations of Daz installers are affected, meaning they will not run. It turns out that I did have some files with the extra junk at the end, but they ran anyway. These were the last 2 recent generations of installers. The last clean download I had was the Ultralight on 5/16/2012. Anything I downloaded after that does have the junk in it, but I didn't download any of the older installers after that date. I took one of my old installers that I downloaded before 5/16 and was clean then "broke" it with the break script, and the fix script fixed it. If anybody has files that need breaking, I can do that too. :rolleyes:
