1. Launch the App with Administrator Privileges

A straightforward solution to bypass this error is to run the app with elevated permissions.

1. Right-click the app's desktop shortcut or executable, then choose "Run as administrator."

2. Confirm by clicking "Yes" on the User Account Control (UAC) prompt to allow the program to modify the PC. Hopefully, it will start without any issues.

3. Unblock the App via Properties

If the app you're attempting to run originates from an unknown publisher online, Windows might block it to ensure your computer's safety. You can unblock it using the "Properties" dialog.

1. Right-click the app and select "Properties" from the context menu.

2. Navigate to the "General" tab, check the "Unblock" box, and click "OK" to apply and save the changes.

Tip: If the Task Manager has been blocked by an admin, find out how to resolve it.

3. Launch the App via Command Prompt

Another approach is to try launching the app through Command Prompt.

1. Enter "cmd" in the Windows Search box, then select "Run as administrator" on the right.

2. Press Win + E to open File Explorer and navigate to the directory containing the app's executable (.EXE file).
3. In this example, we're launching PowerToys from Command Prompt. The .EXE file is located in "Program Files -> PowerToys."

4. Right-click on the folder path and choose "Copy as path."

5. In Command Prompt, enter the following command. Replace [path] with the path you copied, then press Enter.

<code>cd file [path]</code>

6. Proceed with this command and press Enter. Substitute [file name] with the .EXE file's name. In our case, it's "PowerToys.exe."

<code>Start [file name]</code>

4. Deactivate Microsoft Defender Real-Time Protection

If Microsoft Defender is your primary antivirus, it might flag the app as potentially harmful and block it. If you trust the app, try disabling Microsoft Defender's real-time protection and attempt to launch the app again. Consider installing a third-party antivirus instead, as leaving your Windows PC unprotected is not advisable.

5. Turn Off Reputation-Based Protection for Apps

SmartScreen, a Windows Security feature, safeguards your computer from malicious apps and websites by verifying reputable apps to prevent running potentially unwanted apps (PUAs).

If SmartScreen's reputation-based protection malfunctions, it might mistakenly label a trusted app as unwanted, triggering the error and preventing its launch.

1. Search for "reputation" in the Search bar, then click on the top result.

2. Toggle off "Check apps and files."

3. Scroll down and toggle off "Potentially unwanted app blocking."

4. Try running the app to see if it works now.

5. Update the App

You might want to update the app in case a bug is causing the error. Some Windows apps will notify you of available updates upon launch. For others, you'll need to visit their download page to check for new versions and install them.

If you downloaded the app from the Microsoft Store, you can update it there.

1. Type "store" and click on "Microsoft Store" in the search results.

2. Select "Library" at the bottom of the left menu, then click "Get updates" in the top right.

3. The Microsoft Store will scan for apps needing updates and update the one you're trying to run if necessary.

FYI: Learn how to stop Windows apps from accessing the Internet if required.

7. Resolve Microsoft Store App Problems

You can also use the Microsoft Store to repair or reset the app.

1. Press Win + I to open the Settings app.
2. Go to "Apps -> Installed apps," click the three vertical dots next to the app, and choose "Advanced options" from the menu.

3. Click "Repair," then see if the app runs without the error message.

4. If there's no improvement, click the "Reset" button. Note that this will revert the app to its initial state upon installation, and you might lose some data.

5. Confirm by clicking "Reset" in the pop-up.

6. Launch the app to check if the error message persists.

7. Disable Admin Approvals in the Local Group Policy Editor

By eliminating the need for admin approvals, you might bypass the error and launch the app.

1. Press Win + R to open a Run dialog, enter gpedit.msc, then click "OK."

2. Navigate to "Computer Configuration -> Windows Settings -> Security Settings -> Local Policies -> Security Options" in the Local Group Policy Editor.

3. Double-click the "User Account Control: Run all administrators in Admin Approval Mode" policy on the right.
4. Select the "Disabled" radio button, then click "OK."

Tip: Check out this list of registry tweaks to enhance your Windows experience.

9. Disable Admin Block in the Registry Editor

If disabling admin approvals didn't work, try editing the registry.

1. Open a Run window again, enter regedit, then click "OK."

2. Click "Yes" on the UAC warning to allow the Registry Editor to modify Windows.

3. Navigate to "HKEY_LOCAL_MACHINE -> SOFTWARE -> Microsoft -> Windows -> CurrentVersion -> Policies -> System" in the Registry Editor. Double-click the "EnableLUA" value to edit it.

4. Enter "0" in the value data box, then click "OK."

5. Restart your computer to see if the app launches successfully.

6. To re-enable the admin block, return to the "EnableLUA" value in the Registry Editor and set the value data to "1."

7. Attempt Running the App Using the Hidden Admin Account

Many Windows users are unaware of the hidden admin account on their PC, which has extensive permissions. To access it, enable the Super Administrator account on Windows via cmd, then try running the app. Remember to disable the account afterward.

Tip: If you need to change the administrator in Windows, check out our guide that outlines several methods to do so.
