Are you trying to upgrade an installation you ditributed previously? If so it is recomended to use "Upgrade Paths" because

1. Otherwise you will have TWO entries in Add/Remove Programs for your product
2. Upgrade Path will totally uninstall the previous version so overwriting files won't be an issue.

Do these ocx files by any chance have the "Never Overwrite" property set? Are they installed to the [SystemFolder] on Win2K or WinME? If so they MIGHT be protected by System File Protection. Are the version numbers of the ocx's greater than the one's from the previous install?
