What version of Premiere Elements are you using and on what computer operating system is it running?
What are you trying to update ?
a. Camera Raw
b. Program version update
In recent versions, the user is forced to do the updates via the programs Help Menu/Update which may or may not have problems as evidenced by the type of error message that you present.
But, if you have an earlier version of the product, the Premiere Elements answer to as Premiere Elements question may be as simple as downloading the update from Adobe.

If Premiere Elements 9 to 9.0.1 Mac
If Photoshop Elements 9 to 9.0.1 Windows

The Premiere Elements (video editing) answers will be in your specific details. Photoshop Elements questions are best directed to the Adobe Photoshop Elements Forum
We look forward to your details and the outcome of the issue.
