Windows 7: Error 1722

09 Jan 2011   #1

Windows 7
Error 1722

I just reinstalled Windows 7 Professional Academic 64 bit, custom install after deleting the partition and format, on a Dell studio xps 435mt i7 920 with 8 Gb of RAM.
When attempting to install Dragon Naturally Speaking 11, at the end of the install, the "Error 1722 There is a problem with the Windows Installer package. ... Action JustExitVista, location C:\...]natspeak.exe -JustExit." occured.
I checked the Nuance website and made sure that DEP was set to only Windows core programs.
SFC /scannow showed the following files could not be repaired:

I extracted these from the install DVD, and was able to copy the first three into the system32 folder. Ater rebooting, the last two are still listed as corrupt.

There is also a problem with Windows Media Center, the update download for Internet TV will not complete. The download process begins, but won't complete.
The event log has all the updates "Processing of xxx is complete", but on the second to last line "Errors during the last update". The help videos in Media Center will not play.

Microsoft Office 2010 is installed and working fine.

And, when installing Nuane PDF Converter 7, the PdfPro7Hook.exe will crash. I mention this, because this file began having problems before I rebuilt the system. There were a couple of lock-ups this past Fall, so I replaced and increased the amount of RAM. The RAM is recognized and will pass the memory diagnostics test that is an option on the Windows install DVD.

Any idea what is causing the install error or preventing Internet TV from downloading updates?

Thank you
