Autodesk Withdraw AutoCAD 2013 Service Pack 1
Autocad 2013 service pack has now been released for both the full and LT versions of this popular software package but these have quickly been temporarily withdrawn as they are causing a fatal error in some circumstances.
This has become apparant very quickly after the release so hopefully only a small number of installs will be affected.
Autodesk have stated that they actively working to resolve issues this is causing and will re-release the service pack once fixed, but in the meantime best advice is to unistall the service pack if already installed until a fixed version is available.
If you have a pending deployment and have already downloaded these service packs please postpone any re-install until the fixed versions are available.
