OneNote Requires Tablet PC Edition 2005 with Service Pack 2, what is that?

We have an internal email distribution list where people can ask questions to the OneNote product team and over the past months there have been a few emails about this error:

OneNote requires Microsoft Windows Tablet PC Edition 2005 with Service Pack 2 in order for inking functions to work properly. You can install Service Pack 2 from the Windows product pages on the Microsoft Web site.

When this occurs this is just because of an unregistered DLL and you can fix it by doing the following:

  1. open up a command prompt (on Vista make sure it is an elevated command prompt)
  2. cd "%ProgramFiles%\Common Files\Microsoft Shared\Ink"
  3. "regsvr32 /s inkobj.dll"
  4. Close and restart OneNote

This should fix the problem you are having. Ideally you should never see this but I am hoping that by blogging this if you search on Windows Live or Google you will see this link and you can fix your problem : )
