A simpler step would be to use SFC.
Click Start, point to Programs, point to Accessories, point to System Tools, and then click System Information.
On the Tools menu, click System File Checker.
Click "Extract one file from installation disk," type the name of the file you want to extract in the "Specify the system file you would like to restore" box, and then click Start. This means type the files that are missing exactly into the box
In the Restore From box, type the path to the Win98 folder on the Windows 98 CD-ROM. Type the destination folder in the Save File In box if necessary, and then click OK.
Click OK, click OK, and then click Yes when you are prompted to restart your computer.
