How to Resolve the “The System Administrator Has Set Policies to Prevent This Installation” Error on Windows 10/11/8/7
If you’ve encountered the frustrating message stating, “The system administrator has set policies to prevent this installation” while trying to run an MSI installer file on your Windows machine, you’re not alone. This error often arises due to a specific policy setting within the Windows registry that restricts software installations. In this guide, you will learn step-by-step how to edit the registry to resolve this issue, allowing you to install your desired applications seamlessly.
Step 1: Open the Windows Registry Editor
To begin the resolution process, you need to access the Windows Registry Editor. Follow these steps:
- Press Windows + R on your keyboard to open the Run dialog box.
- Type
regeditand hit Enter to launch the Registry Editor. If prompted by User Account Control, click Yes to allow access.
Accessing the Registry Editor is crucial, as this is where you will make the necessary changes to resolve the installation issue.
Step 2: Navigate to the Correct Registry Path
Once you have the Registry Editor open, you must navigate to the following registry path:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows
To do this, you can either manually expand each folder in the left pane or copy the path above, then paste it in the address bar at the top of the Registry Editor window and press Enter.
Step 3: Check for the Installer Folder
Next, look for a sub-key named Installer under the Windows registry folder. This key controls the installation policies:
- If the Installer folder exists, right-click on it.
- If it doesn’t exist, you will need to create it. Right-click the Windows folder, select New, then choose Key, and name it Installer.
Step 4: Modify the DisableMSI Value
Within the Installer folder, check if there is a value named DisableMSI. This value determines whether installations are allowed:
- If DisableMSI exists, double-click it and set its value to
0to enable MSI installations. - If it does not exist, create it by right-clicking in the right pane, selecting New, then DWORD (32-bit) Value. Name it DisableMSI, and set the value to
0.
Changing this value is a critical step in allowing the system to accept MSI installations again.
Step 5: Exit the Registry Editor and Restart Your Computer
After making the changes, close the Registry Editor. It’s important to restart your computer for the changes to take effect:
- Click Start, then select the Power icon, and choose Restart.
Once your system restarts, try running the MSI installer again to check if the error has been resolved.
Extra Tips & Common Issues
If you continue to face difficulties after following the steps above, here are some additional tips:
- Always back up the registry before making any changes. You can do this by clicking on File > Export within the Registry Editor.
- If you cannot see the Installer folder, ensure you are in the correct location:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows. - Check for any group policy settings that might be preventing installations, which may require administrative access to change.
By following this guide, you should be able to fix the “The system administrator has set policies to prevent this installation” error, returning your software installation functionality. If you have further questions or encounter other issues, feel free to seek additional resources or advice tailored to your specific needs.

Can I reverse the changes I made in the registry?
Yes! If you ever need to revert the changes, simply return to the DisableMSI value and set it back to 1 or delete the Installer folder entirely if it was newly created.
What if other installation errors occur after this fix?
