When I go to install PPD, I have NET Framework and Direct X both installed and did the tweak tool. But when i go to install, it starts to install everything PPD needs but stops on IPA Font and says,"This installation package could not be opened. Contact the application vendor to verify that this is a valid Windows Installer package" then I click Ok. Then another message pops up and says,"Your OS is detected as Windows 7 or 8. Please refer following page, and change decoders setting." Then it gives me a link to a thread on PPD website. I followed what it said to do but it still does the same thing. I have Windows 8, so is there a certain way to install PPD on windows 8? If anyone knows what to do please help me out...
