C005: Windows 2000 seems to have a few difficulties!

You could try issuing these commands:

regsvr32 mshtml.dll
regsvr32 shdocvw.dll -i
regsvr32 shell32.dll -i 

sfc /purgecache
sfc /scannow 

I did that, but it told me to insert my Windows 2000 CD. When I did, it told me it was the wrong disk!

Try it in a different CD drive...
