Unable to install due to controlled folder access

Offline Installer:

Error Message: Controlled folder access appears to be enabled on your machine. The chosen install or samples location (for example, Public Documents) is protected by controlled folder access settings.

Controlled folder access - offline

Online Installer:

Error Message: Controlled folder access seems to be enabled in your machine. The provided install, samples, or download location (e.g., Public Documents) is protected by the controlled folder access settings.

Controlled folder access - online

Reason:
Controlled folder access is enabled on the computer and is preventing the installer from writing to protected locations.

Suggested Solution:

Option 1: Temporarily Disable Controlled Folder Access

  1. By default, demos are installed in the Public Documents folder.
  2. When controlled folder access is enabled, demos cannot be installed in the Documents folder.
  3. To allow installation in the Documents folder, follow the steps in this Microsoft article to temporarily disable controlled folder access or allow the installer.
  4. Re-enable controlled folder access after the Syncfusion® setup completes, if desired.

Option 2: Change Installation Directory

If you do not want to disable controlled folder access, install the demos in another directory that is not protected by controlled folder access.
