Does anyone know what the initpki.dll used for?

[jbarker1]

I keep getting the following error message when I try to restore my XP install by doing an upgrade:

Error:
Setup had problems registering the following OLE control DLL:

C:\WINNT\System32\initpki.dll

Contact your system administrator, who may provide assistance in diagnosing this problem.

The next error below this is:

The signature for Windows XP Home Edition Upgrade is invalid. The error code is 426.

The service has not been started.

What service?

I tried registering the dll manually using regsvr32 but it didn't help.

Any ideas?

While i'm not sure what that file is, you may need to either repair your installation, or do a clean reinstall.

I was afraid of that. This is my laptop and I am trying to copy over all my important files to my D drive to do a complete fresh install. I really didn't want to have to do that but it is leaning more and more to that direction.

Initpki.dll is used by the Windows crypto system and it deals with signatures and encryption. I suppose failing is very the reason why the Upgrade signature can't be verified
