nvcpl.dll error at startup - how to fix it!
after installing the drivers for my recently bought nVidia GeForce MX 4000 I got a persisting error message at startup: rundll wasn't able to run the nvcpl.dll because of missing components. As a result, also I wasn't able to acceess all grafic cards options, since the display adapter / the tab for the new grafic card was missing in display-propeties-advanced. Reinstalling the most current version of the drivers and so on didn't help. I had a hard time finding a solution for this problem, it took me several hours of surfing and trial and error. Since I read so many posts around the net with proposed fixes for the problem that didn't help in my case in any way, I thought I post the solution I finally found well hidden in some other forum. Maybe I can save someone else having the same problem some time and nerve, by reposting in this more prominent forum! :-)
In my case, i.e. Win98 (don't know if it's working for other window versions as well), all I had to do was to install the Accesibility ("Eingabehilfen" in German) features of Windows. Like the magnifier lense and that stuff. You can install it via Start-ControlPanel-Software-WindowsSetup. I have no idea what files of the Accesibility setup finally helped nvcpl.dll to load - but IT WORKED! :-) Just give it a try if you have the same problem with nvcpl.dll - I didn't believe this solution myself at first, but my system is up and running fine again... you wouldn't believe how happy I'm about that after HOURS of fruitless trying.
Btw, I often read the "solution" to just throw nvcpl.dll out of the autostart using msconfig - that cures just the sympton, but not the cause. Sure, you won't get the error message at startup anymore, but you still won't get this nVidia-tab in the display properties and thus can't tune all the settings of your grafic card (like TV-out and so on).
All the best,
DocGreebo (aka nvcpl.dll) ;-)
