When you start Windows 98, you may receive the following error messages:
Error loading powrprof.dll.
The system cannot find the file specified.
These error messages may occur even if you disable LoadPowerProfile on the Startup tab in the System Configuration Utility tool (Msconfig.exe).
Error Starting Program
A required .DLL file, POWRPROF.DLL was not found.
This behavior can occur if the Powrprof.dll file in the Windows\System folder is missing or damaged. This issue can also be caused by a missing registry key.
To resolve this issue, rename the Powrprof.dll file (if it exists) in the Windows\System folder, and then extract a new copy of the Powrprof.dll file from your original Windows 98 CD-ROM into the Windows\System folder using the System File Checker tool. To start the System File Checker tool, click Start, click Run, type sfc.exe in the Open box, and then click OK.
