Missing or Corrupt Display Driver

[dderoeck]

I have a OS Windows 7 64 bit PC with MAP 3D 2010 (64x) and CIVIL 3D 2010 (32x) installed on it.

On Map 3D 2010 (64x) SP1, I have installed the VBA Manager Enabeler (extra to be dlled)

When I start Autocad (Map or Civil) I load the following acad.dvb from the same folder

Sub AcadStartup()
AcadApplication_Events
LoadDVB "D:\acad2kx\custom\vba\PDFArchive.dvb"
Exit sub

CIVIL 3D 2010 32x opens normal without problem.

MAP 3D 2010 64x opens with an error:
Display Driver file (.hdi) is missing or has been corrupted
This problem may be caused by missing .hdi files in the following location:
C:\program Files (x86)\AutoCA Civil 3D 2010\Drv\

(I have no error if Civil 3D is started before I start Map 3D)

This error occurs not only on the first action: AcadApplication_Events
but also on if the first function should be: LoadDVB "D:\acad2kx\custom\vba\PDFArchive.dvb"

I have no error if I modify the AcadStartup into

Sub AcadStartup()
MsgBox "test"
Exit sub

Does anyone has the same problem?
Which Driver should be missing?

Its hard to say, but it sounds like a problem of load order. Something, is being called before everything is loaded. acad.lsp gets loaded before the dvb. Normally, vba gets loaded the first time you make a reference to a command like LoadDvb. I use acad.lsp to preload vba using (arxload "acvba.arx"). It might help.

I'm seeing some pretty severe issues with VBA on Win7 64-bit workstations. We have user profiles that somehow get a minor corruption at some point and from that point out if you attempt to load DVB files in S::Startup, AutoCAD will fatal.

I've also seen where having VBA code loaded can cause AutoCAD to not restore once it is minimized. Again, this is only on Win7 64-bit workstations.

It is bad enough that I'm accelerating our port to .NET and leaving VBA behind.

Thank you for those 2 reactions.
The idea of the load order is new to me and i shall study it.

I also will install a virtual WIN 7 (64x) OS on the same PC with only MAP 2010 3D (64x) on it.
Maybe the combination of both soft on the same PC gives also the problem

Problem solved.
Apparently there is a missing driver that is automaticly downloaded and installed by Autocad MAP.
Since there is a firewall active, this driver could not be installed.
By coincidance I had to install a deployment of Autocad 2010 MAP and Civil on the Win 7 64 bit PC for which I needed to bypass the firewall. The PC stayed in this configuration when I launched MAP 2010, with no more error message on the Missing or Corrupt Display Driver.
