Layer Manager Error Message

OK. We at Key Systems are working on this with Autodesk to see if there is a fix to this problem. It appears to be linked to an update of Microsoft .NET which the layer manager has used since ACAD 2006. If you are on the full version of AutoCAD you could try setting the layer manager from the palette option back to the legacy setting LAYERDLGMODE = 0. If this fails, let me know. As soon as we get a solution to the palette option I will post it here.

Thanks Mike for the information.

Couple of things to try.

1. Make sure you are on the latest service packs for AutoCAD 2009 (or your vertical product). These are available from the Autodesk website http://www.autodesk.co.uk/adsk/servlet/index?siteID=452932&id=9298358 (Select product then see Data and Downloads)

2. Uninstall .Net 3.5, and clean up any files left behind then reinstall the .NET on the AutoCAD installation disk. There is this third-party utility which can perform an uninstall of all .NET Framework versions and clean up left over files and folders. This is not an Autodesk or Microsoft utility so use at your own risk, although Autodesk state that it has not caused any known issues (yet).

Then, try installing .Net from AutoCAD's installation disk, or directly from Microsoft's website.

Microsoft .Net 3.0 is located in this folder of AutoCAD installation disk, typically:

D:\x86\support\dotnetfx\dotnetfx.exe or D:\x64\support\dotnetfx\netfx64.exe (for 64-bit systems)

Let me know if this sorts it for you?
