Thanks for the more detail information. I tried exactly what you said. It didn’t work.

If I put the CD into my computer, the start_here.exe would be loaded. Anyway, I tried to load this manually. I can read any pdf by double click. And then, I close the adobe professional 7.

The problem I got from this thread means the problem I got from here, right? I renamed it to notepad.exe. I put this program in another different folder from the real adobe. And then I followed what you told me to do. Those pdf files have been upload to my desktop successfully. But none of them could be opened. It seems that the new created PDF which you just opened would be damaged. (because adobe said that) Those new created PDF which you didn’t open would be blank. I am not sure if I have to use some program to fix those PDFs.

By the way, I have tried to use this problem to dump normal PDFs, I didn’t make it. The new created pdf can’t be opened too. Maybe this is the issue. I have no idea.
