I'm running into a problem on an installation, when my setup file goes to install the run time files oleaut32.dll(sometimes others to) is write protected on the end user's PC, i know you can just change the read only property of the .dll itself and then re-run the setup but i don't want the end user to have to do this, is there any way to have it overwrite the older version anyway???

The .dll versions i'm installing are more recent than the existing ones in the couple of PC's i've ran into this problem on
