Since I cleaned up my PC some weeks ago (drive cleaner, file wiper, defrag), when now starting up Radar Contact , I always get the message "cannot find nDac base pro.msi" or something to that extent. By clicking "Cancel", RC continues to load, and works fine, so no real problem so far. But now by trying to install RC 4.2, I get the same message, and since the file "nDac base pro.msi" cannot be found anymore on my PC, I can only abort the installation. Does anyone have an idea how to tackle this? Many thanks on beforehand, Juul Tango,Hasselt, Belgium.

Far from a computer expert here, but you could try re-installing the nDac map software and see what happens.

I do not remember having installed nDac base pro. Could it be that this software is installed together with Radar Contact?Juul Tango,Hasselt, Belgium

no, i've never heard of it.a quick google search, found thishttp://www.navigraph.com/navigraph/osc/mai...play=node&id=20have you installed this piece of software? and then uninstalled it?jd

Just wanted to confirm that that is the only nDac I know of. I myself have it. Haven

Never, as far as I know, installed nDac pro.Uninstalled RC (and ASV6), deleted all files in nDac folder and re-installed RC (and ASV6) - no problems anymore....Kind regards,Juul Tango,Hasselt Belgium.

ndac pro is probably a database that was installed with navigraph. did you install navigraph at some point?doesn't matter, glad to see everything is working.jd
