Access 2003 Runtime Issue

We created a small Project log App in Access 2002. and upsized it to SQL Server . We then upgraded Office to 2003 and installed the Access Developers extensions so that we could publish the app to users without Access. On some PCs rumming Win2k and Office 2002, the app installs and runs fine. On other Win2K boxes with Office 2002, the app gens an error that it is pointing at a missing or broken link to OCW10.DLL. The DLL is in the same directory on the machines that do not work as it is on the ones that do. We cannot identify a cause. (It may be because this is our first tryat thisuse of access). Any thoughts on why it is complaining would be appreciated.
