Since I cleaned up my PC some weeks ago (drive cleaner, file wiper, defrag), when now starting up ASv6 (and also Radar Contact) , I always get the message "cannot find nDac base pro.msi" or something to that extent. By clicking "Cancel", ASv6 continues to load, and works fine, but it is not really the right way to do.Could it be that nDac base pro is installed by the first install of AS? How can I remedy to this?Does anyone have a good idea?Many thanks on beforehand,Juul Tango,Hasselt, Belgium.

Hi,Looks like your Windows registry is messed up. When you start ASv6 it is looking to start the installation file for nDac base pro.I did a Google search and that program looks to be a navigation chart program. Do you remember purchasing and installing it?I can suggest that you totally uninstall ASv6 and then reinstall. Maybe this will fix your registry.Please let us know.
