I’ve been having the following problem for months:

Whenever I go into XP’s Power settings dialog box, clicking on the Sony Power Management Viewer will always generate an error:

“Run a DLL as an App” has reported a problem…

The error signature is:
AppName: rundll32.exe AppVer: 5.1.2600.2180 ModName: unknown
ModVer: 0.0.0.0 Offset: 00b0e7e2  

I’ve verified that uninstalling Sony Power Management (and the associated Viewer) solves the problem.

Does anyone have a similar error? My Power Management is Version 1.6.01.14010. Is this the latest version?

rundll32 ... bad sign.
