Inventor 2023 installer has insufficient privileges to access AdSSO


Installing Inventor Professional 2023 as administrator the following error pop-ups preventing the installation from completing.

‘The installer has insufficient privileges to access this directory:
C:\Program Files\Autodesk\Autodesk AdSSO.  The installation cannot continue.  Log on as administrator or contact your system administrator. 
Cancel. Retry.’


The installer files don’t have sufficient permissions to the AdSSO component installation folder in
C:\Program Files\Autodesk\Autodesk AdSSO.

Previous failed installations may have caused access problems to the folder and the installation folder is empty as well.



Log in as user with administrative rights.

1.Get a full download of Inventor Professional 2023 from your Autodesk Account: 

2.Run the AdSSO.msi installer manually before installing Inventor Professional 2023:

Eg from the download folder in

  • C:\Autodesk\Inventor_Pro_2023_English_Win_64bit_Dlm\x64\AdSSO\AdSSO.msi
  • C:\Users\user_name\Downloads\Autodesk\Inventor_Pro_2023_English_Win_64bit_Dlm\x64\AdSSO\AdSSO.msi

3. If the AdSSO installation fails with the same error try overwriting  permissions to the system folder C:\Program Files\Autodesk using this method:

4.Once the AdSSO.msi runs and successfully completes the Autodesk Single Sign-On installation, proceed with installing Inventor 2023.
