To convert other format files (such as DOC, PPT, etc.) to PDF with Adobe Acrobat Professional, you must open the Print Spooler service in the service option, preferably set to automatic, boot automatically open service, so don't every time Manually open the service.
When I installed Adobe Acrobat Professional 7.0, my Print Spooler service was disabled, so she installed several times without success, then set it to manual, successfully installed, but then I would like to use the Convert to Adobe PDF in the right button, or Directly do new PDF directly in Adobe Acrobat Professional, it is always said, "Unable to open the original file, fix the Adobe Acrobat Professional may be able to solve this problem", fortunately, I don't eat this set, I don't reinstall it. Just open the Print Spooler service.
