Installation Requirements

- Autodesk Inventor 2020 supports Windows 7 SP1 64-bit and Windows 10 64-bit.
- 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 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.
- 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.
- 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.
- 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.
- 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.
- Autodesk Vault Basic 2020 is delivered as a separate installer. Customers who use Vault Basic may download both the Basic Client and Basic Server from [Autodesk Account].
- File In Use dialog about Autodesk Analytics Client Service may pop up during product uninstall or reinstall. You can safely continue by clicking Ignore button.
- Use the Autodesk Uninstall Tool to uninstall Inventor. Uninstalling Inventor from the Control Panel may result in the File in Use dialog box prompting you to close Autodesk Analytics Client Service. In this workflow, click Ignore to complete the process. NOTE: We recommend you close all Autodesk products before beginning the uninstall process.

Notes:

* Autodesk Inventor is optimized to take advantage of the SSE2 extended instruction sets supported on Pentium 4, AMD Athlon 64, and AMD Opteron processors. Inventor 2020 will not install on computers that do not support SSE2. Several utilities are available on the Internet that report CPUID including supported instructions sets.
** Autodesk recommends settings which allow Microsoft Windows to manage virtual memory as needed. There should always be at least twice as much free hard disk space as system memory (RAM).
