- Ensure you are installing/uninstalling and using the product with enough rights to do so (install and reinstall as local administrator): Unable to run AutoCAD® as a restricted user http://usa.autodesk.com/getdoc/id=TS1055299

- Reset AutoCAD Settings as follows:

- Install the latest service pack: http://usa.autodesk.com/support/downloads/

- If the issue persist, please create a new local user account onto the computer and give it administrator permissions then log into the computer with newly created test account and see if AutoCAD launches properly under this user account as well.

- If AutoCAD also has issues under the test user account, you will need to do a complete uninstall and re-install following these instructions:

- More complete .NET fix may be necessary ahead of the uninstall/reinstall process (error 1603): http://forums.autodesk.com/t5/Installation-Licensi​ng/NET-Framework-Cleanup-Tool-for-Unhandled-Except​...
