.Net Framework issues in Autodesk Map 2005+ 

Issue:

During the past few years, many software publishers have been developing products in a platform called Microsoft Visual Studio .Net. The majority of new products released in the next several years – including those from R&R Sy-TEC, will have been developed in this environment.  

For a computer to run such applications, a utility program must be installed called the .Net Framework Common Language Runtime, or CLR. The CLR is invisible to end users, and it’s installation is handled automatically at the time an application program requiring it is installed. End users do not normally need to be aware the CLR even exists. However, there is a design issue in Autodesk Map 2005 & 2006 that can change this.  

Some functions of Map 2005+ use the CLR. Furthermore, the program is designed to seek out and use the highest version of the CLR installed on the computer (multiple versions can be installed). The problem is that Map 2005+ is not compatible with CLR versions 2.0 and higher.

Symptom:

After a new (non-AutoCAD) product is installed, Map 2006 will crash when the user invokes certain functions – such as CUI (Custom User Interface) and VTOPTIONS (Visual Transition Options).

 Solution:

Autodesk has provided a work-around that locks down AutoCAD Map to the highest compatible version of the CLR. To employ this solution, open the file acad.exe.config in Notepad; the file is usually located in:  

C:\Program Files\Autodesk Map 3D 200X\ 

The original text of the file will look like this:

Copy the text highlighted in yellow above, and paste it into a new line below the “-->”. After doing so, the file should look like this:

Save the file, and re-start AutoCAD Map.
