Fix 1: Use Another Installer File
Try using a new installer file and then check if the installation completes without an error. To avoid any problems, re-download the app’s installer file from the official website.
Step 1: Open File Explorer > navigate to the Downloads section > right-click on the installer file > select Run as administrator.
Step 2: The User Account Control window will pop up. Click on Yes to launch the installer file with administrator rights.
Step 3: Check if the error pops up now.
Fix 2: Restart Windows Installer Service
If the service glitches and stops working properly, you can’t install these packages and will see the error message. Restarting the service will help.
Step 1: Press the Windows key to open the Start menu. Type services in the search bar and press Enter to launch the Services utility.
Step 2: Scroll down and find the Windows Installer service. Right-click on it and select Restart.
Fix 3: Temporarily Disable User Account Control
User Account Control can sometimes act overprotectively and prevent installers from running. So, you must temporarily disable the feature to install the app and re-enable it once the job is complete.
Step 1: Press the Windows key to open the Start menu. Type UAC in the search bar and press Enter to open the User Account Control.
Step 2: Drag the slider down to the bottom and click on OK.
Step 3: The User Account Control window will pop up. Click on Yes.
Step 4: Reattempt the installation and ensure to re-enable User Account Control settings afterward.
Fix 4: Fix Group Policy Editor Settings
Changes in a system policy can prevent you from installing apps and result in an error message.
Step 1: Press the Windows key to open the Start menu. Type gpedit.msc in the search bar and press Enter to open the Group Policy Editor.
Step 2: Navigate to the Computer Configuration section on the left-hand side. Click on Administrative Templates.
Step 3: Click on Windows Components.
Step 4: Scroll down and click on Windows Installer on the right.
Step 5: Double-click on the Prohibit non-administrators from applying vendor signed updates policy to open its properties.
Step 6: Select Disabled > click on Apply > OK.
Step 7: Close the Group Policy Editor and restart your PC to apply the changes.
Fix 5: Edit System Registry
If you use the Windows 11 Home version, you must use the Registry Editor to disable the policy. But before doing that, create a registry backup and proceed with this method.
Step 1: Press the Windows key to open the Start menu > type regedit in the search bar > press Enter.
Step 2: The User Account Control Window will launch. Click on Yes to open the Registry Editor.
Step 3: Go to the address bar at the top, paste the following path, and press Enter:
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows
Step 4: Right-click on the Windows key to open the context menu. Click on the New option > select Key.
Step 5: Name the key Installer and press Enter.
Step 6: Navigate to the right pane. Right-click on the empty area and click on New. Then, click on DWORD (32-bit) Value.
Step 7: Name the newly created DWORD value as DisableLUAPatching.
Step 8: Double-click on the DWORD value to open the Edit window. Type 1 in the Value Data text box and keep the base as hexadecimal.
Step 9: Click on OK.
Step 10: Close the Registry Editor and restart your PC to apply the changes.
Fix 6: Re-Register the Windows Installer Service
If changing the policy has no effect, re-register the Windows Installer service using the Command Prompt.
Step 1: Press the Windows key to open the Start menu > type cmd in the search bar > press Ctrl + Shift + Enter at once.
Step 2: The User Account Control window will pop up. Click on the Yes button to open the Command Prompt with administrator rights.
Step 3: Type and press Enter to execute the following commands one by one:
%windir%\system32\msiexec.exe /unregister
%windir%\system32\msiexec.exe /regserver
%windir%\syswow64\msiexec.exe /unregister
%windir%\syswow64\msiexec.exe /regserverStep 4: After the commands finish execution, close the Command Prompt window and restart your PC.
