Inventor LT 2019

This readme contains important information regarding the installation and contents of Inventor LT 2019.

Autodesk Inventor LT 2019 supports Windows 7 SP1 64-bit, Windows 8.1 64-bit and Windows 10 64-bit. For more information, please refer to System requirements for Autodesk Inventor LT products.
Windows 7 SP1 requires MS KB update (4019990). If not already present on the machine and/or if MS Updates are disabled, this KB update will need to be applied prior to installing Inventor.
If you download the source files to a local folder with a name that contains non-English characters, ensure that the language in Regional Settings is consistent with the language name of the local folder.
Make sure the Inventor install path does not contain double-byte characters when installing Inventor on a single-byte operating system.
Installation is sometimes slow due to Microsoft security update KB2918614. If so, the installation will require 2-3 hours to complete. For more information, please refer to Microsoft support page.
If you are using Windows 7 on a 64-bit system, please verify that you have the Microsoft fix for user mode callback exceptions KB976038. This fix ensures that Autodesk receives the correct data from Inventor error reports. For more information, and access to this fix and related Microsoft downloads, see Autodesk Technical Solution 15492718.
A Warning 1946 dialog may be seen during installation. This is a benign Microsoft warning and can be safely ignored. Simply click OK on the dialog.
If the installer prevents you from installing one or more products, pause the cursor over the red "prohibited" circle beside the product name for more information.

If .Net version is not updated to .Net4.7 before installing Inventor LT 2019 on Windows 8.1, please Reboot OS to update .Net version after installing Inventor LT 2019 to ensure Inventor LT 2019 works well.
