Understanding PKN Issues

Troubles Opening PKN Files

Microsoft Systems Management Server Isn't There

When you double-click your PKN file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". Generally, this is experienced in %%os%% because Microsoft Systems Management Server isn't installed on your PC. Because your operating system doesn't know what to do with this file, you won't be able to open it by double-clicking.

Tip: If you don't have Microsoft Systems Management Server installed, and you know of another program to open your PKN file, you can try opening it by selecting from the programs listed under "Show Apps".

Microsoft Systems Management Server Requires Update

Your Systems Management Server (SMS) Package Creation Notification file is incompatible with Microsoft Systems Management Server because you might have the wrong version installed. Visit the Microsoft Corporation website to download (or purchase) the latest version of Microsoft Systems Management Server. The primary cause of this problem is that your Systems Management Server (SMS) Package Creation Notification file was created by a different (newer) version of Microsoft Systems Management Server than what's installed.

Tip: Sometimes you can get a clue about the version of PKN file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).

Regardless, most of the PKN file opening problems relate to not having the right version of Microsoft Systems Management Server installed.
