How to Fix PowerPoint ‘Cannot Verify the License’ Error

You open PowerPoint and see the error message “Cannot Verify the License for This Application.” This error prevents you from using PowerPoint until it is resolved. The cause is usually a corrupted license token, an expired subscription, or a conflict with the Microsoft Office activation system. This article explains why the error occurs and provides step-by-step fixes to restore your PowerPoint access.

Why PowerPoint Cannot Verify the License

The “Cannot Verify the License” error appears when the Microsoft 365 activation service cannot confirm your subscription or product key. This happens for several reasons. The license token stored on your computer may be outdated or corrupted. Your subscription may have expired or the payment method may have failed. In some cases, a Windows update or antivirus software interferes with the activation process. The error can also occur after a major Windows update that resets system files related to Office licensing.

The license verification process relies on a secure token that communicates with Microsoft servers. If this token is missing, damaged, or blocked by security software, PowerPoint cannot confirm your right to use the software. The error message appears immediately on launch or after a few seconds of use.

Steps to Fix the PowerPoint License Error

Try the following fixes in the order listed. Each step addresses a different root cause of the license verification failure.

Fix 1: Sign Out and Sign Back Into Microsoft 365

1. Open any Office app
   Launch PowerPoint or Word. If the error blocks the app, use a different Office app that opens successfully.
2. Go to File > Account
   Click File in the top-left corner, then select Account from the left sidebar.
3. Click Sign Out
   Under User Information, click Sign Out. Confirm the action when prompted.
4. Close all Office apps
   Close PowerPoint, Word, Excel, and any other Microsoft 365 programs.
5. Restart PowerPoint and sign in again
   Open PowerPoint. Click Sign In in the top-right corner. Enter your Microsoft account email and password. Wait for the license to verify.

Fix 2: Run the Microsoft Support and Recovery Assistant

1. Download SaRA
   Go to the Microsoft Support and Recovery Assistant page. Download and install the tool.
2. Select Office
   Open SaRA. On the main screen, choose Office from the list of applications.
3. Choose I’m having trouble installing or uninstalling Office
   Select this option and click Next.
4. Follow the on-screen prompts
   SaRA will detect activation issues and attempt to fix them automatically. Restart your computer when prompted.

Fix 3: Repair Office Installation

1. Open Control Panel
   Press Windows key + R, type control, and press Enter.
2. Go to Programs and Features
   Click Programs and Features under the Programs section.
3. Select Microsoft 365
   Find Microsoft 365 in the list. Right-click it and choose Change.
4. Choose Quick Repair
   Select Quick Repair and click Repair. Wait for the process to finish. If the error persists, repeat the steps and choose Online Repair instead.
5. Restart your computer
   After the repair completes, restart Windows and open PowerPoint again.

Fix 4: Clear Office License Tokens Manually

1. Close all Office apps
   Make sure no Office programs are running.
2. Open Command Prompt as administrator
   Press Windows key, type cmd, right-click Command Prompt, and select Run as administrator.
3. Navigate to the Office folder
   Type cd %ProgramFiles%\Microsoft Office\Office16 and press Enter. For 32-bit Office on 64-bit Windows, use cd %ProgramFiles(x86)%\Microsoft Office\Office16.
4. Run the license clear command
   Type cscript ospp.vbs /dstatus and press Enter. Note the last five characters of the product key shown.
5. Remove the license
   Type cscript ospp.vbs /unpkey:XXXXX where XXXXX is the five-character key from the previous step. Press Enter.
6. Reactivate Office
   Open PowerPoint. You will be prompted to sign in again. Enter your Microsoft account credentials.

If the License Error Persists After These Fixes

PowerPoint shows the error after signing in again

This means the subscription itself may have expired. Go to account.microsoft.com/services and check your subscription status. If it shows Expired or Past Due, renew your subscription. After renewal, sign out and sign back into Office as described in Fix 1.

The error appears only on one user account

If other user accounts on the same computer work fine, the license token for your account is corrupted. Use Fix 4 to clear the token and reactivate. If the problem continues, create a new Windows user profile and sign in there.

Antivirus software blocks license verification

Some antivirus programs block Office from contacting Microsoft activation servers. Temporarily disable your antivirus and test PowerPoint. If the error disappears, add an exception for PowerPoint and the Office activation processes in your antivirus settings.

PowerPoint Online vs Desktop: License Verification Differences

Item	PowerPoint Online	PowerPoint Desktop
License check method	Browser-based sign-in via Microsoft account	Local token verified against Microsoft servers
Error occurrence	Rare; usually due to expired subscription	Common after updates, corruption, or token issues
Offline access	Not available	Works offline after initial license verification
Repair complexity	Clear browser cache or sign out/in	Requires token clearing, repair, or SaRA tool

The “Cannot Verify the License” error affects only the desktop version of PowerPoint. PowerPoint Online uses a different activation system that relies on your browser session. If you cannot fix the desktop error immediately, you can use PowerPoint Online as a temporary workaround.

To access PowerPoint Online, go to office.com, sign in with your Microsoft account, and select PowerPoint. Your files saved on OneDrive or SharePoint are available there. This gives you full editing capabilities while you resolve the desktop license issue.
