It sounds like he may have installed the newer version into the older versions directory by mistake. If that's what happened, there's really no easy way to fix it.
Reguardless of how it happened, the best way to correct the problem would be to uninstall <B>all</B> NI related software using the Windows Add/Remove Programs feature, then start reinstalling, starting with the oldest version of LabVIEW first. Do a Custom install on the older versions and <B>do not</B> install any drivers until you are installing your newest version. This driver set will find the other versions of LabVIEW and install the correct drivers for everything. Hope this helps. Ed
