Earlier in the month the Inventor team has released Hotfix TS1071050 which addressed an issue where the DWG Import Wizard became unstable or ceased to function due to a dialog box stating "End of Evaluation Period." The hotfix was associated with the AOEMViewer (AutoCAD OEM Viewer), one of the sub components of the Autodesk Inventor LT Technology Preview, that is used for importing DWG files.
The other day we updated the Autodesk Inventor LT Technology Preview, ailt.zip, to include the hotfix. This means that people who download this updated version will not have to download and apply the hotfix separately.
This updated installer has been tested in the lab. Our continuing efforts to supply high quality products, including technology previews, are alive in the lab.
