Error 1603 during installation of Autodesk software, To workaround this issue, use the following steps. If one does not help, move to the next one:

If using an Install Now installer for your Autodesk product, try using the Browser Download or Download Now method to get the complete installation package, and then retry the install.

Remnants and residual files of previous installs

  1. Perform a Clean Uninstall to remove any residual files and folders from previous installations.
  2. Attempt to install the software again with Download Now option.
    • If the application fails to uninstall try using the the Microsoft Fixit tool (Works for Windows 8,10 and Windows Server):

Microsoft Visual C++ runtime installation failed

If setup.log indicates that the installation error was caused by a Microsoft Visual C++ runtime installation, refer to the following Autodesk knowledge base article.

A file is locked and cannot be overwritten

A certain file on the machine is locked, or setup attempts to reboot because of a locked file, which fails. To make sure that a locked file is not causing the error, close all applications running in the background, reboot the machine, and run setup again.

The Windows TEMP folders are full

The system temp directory is not clean. This is the temp directory that setup extracts files to and runs from. Either the temp directory does not have an adequate amount of available space, or it has too many files that may conflict with setup files.

Clean the default temp directory and free up hard-disk space by removing unneeded files.

  1. On the Windows Start menu, enter %TEMP% in the “Search programs and files” edit field.
  2. In the Temp folder, press CTRL+A to select all the files and folders contained in the Temp directory and delete them.

Not enough disk space

This error (Error 1603 during installation of Autodesk software) occurs on machines that do not have enough disk space to install the setup and store rollback files. This space is generally required on the root drive even if the setup may be installed to a different drive.

Make sure that there is enough space on the root drive of the machine. This space is required by setup to decompress files in the temp directory and to store rollback information in the Windows directory of the machine. Even though the setup may be installed on another drive, it is imperative that the machine have at least twice as much space as the size of the setup on the root drive (the drive with the Windows operating system installed on it).

Setup files were corrupted during extraction

Exit or turn off conflicting and competing programs, including such things as virus scanners, word processors, spreadsheets, web browsers, system utilities, etc. Then launch the installation again.

Short file name creation is disabled on the target machine

Enable support for 8.3 name creation—e.g., short file names—on the target machine. Navigate to the following registry entry:


An NtfsDisable8dot3NameCreation value of zero (0) enables the short file name creation functionality. A value of one (1) disables this functionality.

Registry modifications require rebooting the target machine for the change to take affect—do this before attempting to launch the setup again.

Note: If the target machine should normally have short file name creation disabled, it can be disabled after the install completes by resetting NtfsDisable8dot3NameCreation to its original value and rebooting again.

Autodesk Installation Diagnostic Assistant (AIDA)

The Autodesk Installation Diagnostic Assistant (AIDA) can provide assistance in identifying the root cause of 1603 Error messages and will offer suggested solution if one is available.

Review Setup

As last resort, review the setup log, check to see if the installer is failing on installing multiple components. E.g. C++ libraries, .NET, core product This could be an indication a security setting is blocking the installation. Disable your antivirus software and re-install.
