Trimble Link – Civil 3D Install Mystery

Recently, i tried installing the Trimble Link for Civil 3D 2008.  Trimble Link is a FREE add-on to Civil 3D that gives you seemless data transfer to Civil 3D and other design programs. Let me preface this by saying that Trimble has a great reputation for making quality products and my experience is no different.  So the install is moving along , waiting to use the tools you see below.






So there i am waiting patiently and I get an error message:

“RegDBQueryKey function failed.”

What the ?  Do what?  At that point all you can do is hit OK and the install stops.  Read on to find out how to solve this mystery should it happen to you!

The first response i got was, my registry is corrupt, reinstall civil 3d and you’ll be good.  I said try again.  I hate that answer by the way.  Then we installed a data transfer utility, that went flawless.  They then suggested i install into an older version and maybe the registry would populate accordingly.

So, being a reseller, i have older versions available.  Now i install Civil 3D 2007 and the Trimble Link installed as advertised.  OK, maybe now the 08 version of TL will work….. nope. Arghh. Ok, so now let’s try Land Desktop 2008 and TL for LDT 08.  That works fine.  Try TL for C3D 08, nope.  Although the message has now changed to:  “Autodesk Civil 3D 2008 cannot be found.”  Obviously a left over error message from the 2007 version.

So, here we are today after several phone calls, emails & debugging and we find a registry key that’s missing.  Hhmmm, maybe this is the trick?  let’s see…

They key is shown below , ACAD-6000:409.  Apparently, when i installed Civil 3D 2008, this key either did not get created or was deleted somehow.


Ok, let’s try the TL for C3D 08 install one more time…..  And it works! Wow, if ever there was a needle in the haystack…

Till next time!
