Unable to install because of another installation

Error Message: Another installation is in progress. You cannot start this installation without completing all other currently active installations. Click cancel to end this installer or retry to attempt after currently active installation completed to install again.

Reason
You are trying to install when another installation is already running on your machine.

Suggested solution

1. Open Windows Task Manager.

2. Go to the Details tab.

3. Select msiexec.exe (it may appear as msiexec.exe *32 on 64-bit systems) and click End task.

Unable to install due to controlled folder access

Offline

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

Online

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. (The Online installer references the additional download location, while the Offline installer does not.)

Reason
Controlled folder access is enabled on your machine.

Suggested solution

Suggestion 1:

1. Our demos are installed in the Public Documents folder by default.
2. Controlled folder access is enabled on your machine, so the demos cannot be installed in the Documents folder. If you need to install the demos in the Documents folder, follow the steps in this link and disable controlled folder access. You can also allow the Syncfusion installer through Controlled Folder Access instead of disabling it entirely.
3. You can re-enable controlled folder access after installing the Syncfusion^® installer.

Suggestion 2:

1. If you do not want to disable controlled folder access, you can install the demos in another directory. In the installer, click Browse on the install location screen and choose a folder that is not protected by controlled folder access.
