If you're seeing this error when trying to install, update, or open the Clickfree program, don’t worry — it’s a common Windows security setting issue and can usually be fixed in just a few minutes.

 Why is this happening?

Windows may block the file for one of these reasons:

• It was downloaded from the internet and marked as unsafe

• Your user account doesn’t have full permission to open it

• Your antivirus or Windows settings restricted access by mistake

 How to Fix the Error Step-by-Step:

You’ll be adjusting file permissions to make sure your computer allows the Clickfree installer to run.

 Step 1: Find the Installer File

1. Open File Explorer
   (Click the folder icon in your taskbar, or press Windows key + E)

2. Go to your Downloads folder
   This is usually where the Clickfree installer was saved

3. Find the file named something like:
   ClickfreeInstaller.exe or SetupClickfree.exe

 Step 2: Open File Properties

1. Right-click the installer file

2. Choose Properties from the menu

 Step 3: Unblock the File (If Needed)

1. In the Properties window, look near the bottom

2. If you see a checkbox labeled "Unblock", check it

3. Click Apply, then OK

Note: If you don’t see an “Unblock” option, that’s okay — move on to the next step.

 Step 4: Check Security Permissions

1. Right-click the installer file again and choose Properties

2. This time, go to the Security tab at the top

3. Under Group or user names, click on your Windows user account
   (This is usually the name you log in with — like John or Danielle)

4. Click the Edit button just below the list

 Step 5: Adjust Permissions

1. In the new window called Permissions for Setup, make sure your user is selected

2. Look for the columns under Allow and Deny

3. Make sure:

   • ✅ All boxes under Allow are checked

   • ❌ All boxes under Deny are unchecked

4. When done, click Apply and then OK

5. Click OK again to close the Properties window

 Step 6: Try Running the Installer Again

Now go back to the file and double-click it to run the installer.

It should now open normally and allow you to continue with the installation.
