I have the same problem.
Autodesk told me to completely remove and reinstall .NET
I was able to remove .Net 3.5 and reinstall, but it still didn’t work.
It is a major pain.
Here are the instructions I was given.
Let me know if you have any success.
1. If you are having problems with .NET Framework I commonly advise
the removal of ALL .NET Framework versions (including service packs and
hotfixes) and then a reinstall of only the version which is relevant for the
version of AutoCAD in question (from the AutoCAD disk if possible). If
other programs have a dependency on a newer version I recommend the customer
run Windows Update, but only after the AutoCAD issue has been diagnosed and
resolved.
2. If there are difficulties with the uninstall or reinstall of .NET
Framework, try it in Diagnostic Mode (see TS75218). I have had much greater
success when working with these installs in diag mode.
3. For 2009 products make sure the “Microsoft Visual C++ 2005
Redistributable” is installed (found in ..\Support\VCRedist on the disk).
This is required for newer .NET Framework components to function correctly.
4. Note that there are different versions of .NET Framework and the
C++ Redistributable for 32 and 64 bit operating systems. Make sure the
correct version is being installed for your operating system.
5. All .NET enabled executables have a “.exe.config” (i.e.
acad.exe.config or dwgviewr.exe.config) file located in the same folder as
the exe which can be configured in Notepad if multiple versions of .NET
Framework are installed. This can be a handy (and easy) suggestion. See
TS1062546 for details on modifying this file.
6. There is a third-party (non-Microsoft) utility which performs an
uninstall of all .NET Framework versions and cleans up left over files and
folders. This utility is useful if manual uninstalls are not working to
resolve the problem. I use this only as a last resort, and I preface it by
saying that this is not an Autodesk or Microsoft utility so use at your own
risk (it has not caused me any troubles though). This is a not a miracle
cure but it is another useful weapon in our artillery.

7. I have encountered a few scenarios where none of these suggestions
are successful in fixing .NET Framework. These are often related to older
systems or machines where Windows is not behaving correctly. If none of the
strategies above are successful it may be necessary for the customer to
contact someone at Microsoft (or their system support professional) for
additional Windows troubleshooting.
For reference, here are some common symptoms of .NET Framework issues. This
list is not all-inclusive.
• Layer manager, tool palette, quick calculator, Style manager,
Project navigator and ribbon issues. These components depend heavily on
.NET Framework
• JIT (Just-in-Time) Debugger errors
• “AutoCAD was not installed properly. Please reinstall
immediately” or “The application has failed to start because its side by
side configuration is incorrect…” errors on startup
• 1935/HRESULT 0x80070002 errors during AutoCAD install or
deployment
• Some (but not all) variations of the infamous FATAL ERROR:
Unhandled e0434f4dh Exception at 7c81eb33h/7c812A5bh
• “NGEN failed to exit” errors during installation
• Vault installation errors
• Exception errors in acmgd.arx or acmgd.dll during startup
• “Class Not Registered” errors
• “Cannot load assembly. Error details:
System.Security.SecurityException” errors at the AutoCAD command line
• “Autodesk ACT libraries were not properly registered” starting 3DS
Max or Viz
• “Error 25015. Failed to install assembly…” during installation
(primarily Inventor)
The following list describes the version of .NET Framework required for
AutoCAD and LT. AutoCAD 2005 and earlier releases did not rely on .NET
Framework.
• AutoCAD 2006 requires .NET Framework 1.1 SP1
• AutoCAD 2007 requires .NET Framework 2.0
• AutoCAD 2008 requires .NET Framework 2.0
• AutoCAD 2009 requires .NET Framework 3.0 SP1
• AutoCAD 2010 requires .NET Framework 3.5 SP1
