When installing a new AutoCAD version on your computer, you sometimes encounter a problem where the target directory already contains another version of AutoCAD.

This situation is usually caused by residual files from a previous installation of AutoCAD, preventing the new installation from successfully completing.


First, we need to remove any previously installed versions of AutoCAD on our computer.

This step may affect other Autodesk software on the computer, so back up the data before performing this operation. After performing this operation, other Autodesk software also needs to be reinstalled.

1. Delete the following folders (if they exist):

   – C:ProgramDataAutodesk

   – C:Program FilesAutodesk

   – C:Program Files (x86)Autodesk

   – %localappdata%Autodesk

   – %appdata%Autodesk

2. Clear the TEMP file:

   – Click the Windows Start button.

   – In the Run box, type %TEMP% and press Enter.

   – Delete all files. Ignore any files in use.

3. Delete the following registry keys (back up the registry first):



After completing the above steps, you can try to install AutoCAD again.

This way, you should be able to install new versions of AutoCAD smoothly without being affected by older versions.

Please note that in order to prevent data loss, it is recommended to back up important data before operation.
