How to Run a PowerPoint Slide Show From a USB on a Restricted PC

You have a presentation saved on a USB drive, but the PC you need to present from has strict software installation restrictions. You cannot install PowerPoint or any other application. Running the slide show directly from the USB without installing software is the goal. This article explains how to use PowerPoint’s built-in Package for CD feature to create a portable presentation that runs on any Windows PC, even without PowerPoint installed.

Why You Cannot Install PowerPoint on a Restricted PC

Restricted PCs in corporate, educational, or public environments block users from installing software. This is a security measure to prevent unauthorized applications. Even if you have a valid license, the system may not allow you to run an installer. PowerPoint is a full desktop application that requires registry entries and system-level permissions to install. Without those permissions, the installer fails or is blocked by group policy.

The workaround is to use the PowerPoint Viewer, a free program from Microsoft that can play slide shows without needing a full installation. The Viewer runs as a standalone executable. You can place it on your USB drive alongside your presentation file. When you plug the USB into the restricted PC, you run the Viewer directly from the USB. No installation is required.

Steps to Package Your Presentation for a USB Drive

These steps assume you have access to a PC with PowerPoint installed. You will create a package on your USB drive that contains both the presentation and the PowerPoint Viewer.

1. Insert your USB drive and open your presentation in PowerPoint
   Open the presentation you want to run on the restricted PC. Save any changes before proceeding.
2. Go to File > Export > Package Presentation for CD
   In the Export section, click the Package Presentation for CD option. A dialog box named Package for CD opens.
3. Name your CD package
   In the Package for CD dialog, type a name for your package. This name becomes the folder name on your USB drive. Use a short name with no spaces, such as MyShow.
4. Add linked files and set options
   Click the Options button. Check the box for Linked files to include videos, audio, and fonts embedded in your presentation. Check the box for Embedded TrueType fonts if you used custom fonts. Under Select how the presentation will play, choose the option that matches your needs: play all presentations automatically or let the user choose. Click OK.
5. Click Copy to Folder
   Back in the Package for CD dialog, click Copy to Folder. A browse dialog opens. Select your USB drive as the destination. Click Select. PowerPoint creates a new folder on your USB drive with the name you provided and copies all files into it.
6. Save your original presentation as a PowerPoint Show (PPSX)
   Open your presentation again. Go to File > Save As. Choose your USB drive folder. In the Save as type dropdown, select PowerPoint Show (ppsx). Click Save. This creates a file that opens directly in slide show mode when double-clicked.

After completing these steps, your USB drive contains a folder with the package and a PPSX file. The folder includes the PowerPoint Viewer executable named PPTVIEW.EXE, your presentation file, and any linked media.

How to Run the Presentation on the Restricted PC

1. Plug the USB drive into the restricted PC
   Insert the USB drive into an available port. Wait for Windows to recognize the drive and assign a drive letter.
2. Open the package folder
   Open File Explorer and navigate to the USB drive. Double-click the folder you created in the packaging step.
3. Run PPTVIEW.EXE
   Locate the file named PPTVIEW.EXE. Double-click it. The PowerPoint Viewer opens. If a security warning appears about running an executable from a network or external drive, click Run or Yes.
4. Select your presentation
   In the PowerPoint Viewer window, browse to your PPSX file or the packaged PPTX file. Select it and click Open. The slide show starts immediately.

If you double-click the PPSX file directly, Windows may attempt to open it with PowerPoint if it is installed. On a restricted PC without PowerPoint, the PPSX file will not open. Always use PPTVIEW.EXE to launch the show.

If the PowerPoint Viewer Does Not Run on the Restricted PC

Windows blocks the executable due to security policy

Some restricted PCs use AppLocker or Software Restriction Policies to block any executable from running from a removable drive. In this case, PPTVIEW.EXE will be blocked. You can try renaming the file extension from .EXE to .COM. Some policies do not block .COM files. If that fails, you must use a different approach: convert your presentation to a video file (MP4) or a PDF file. Both can be opened with built-in Windows apps (Movies & TV or Microsoft Edge for MP4, and Microsoft Edge or Adobe Reader for PDF).

Linked videos or fonts do not play

If your presentation includes linked videos or custom fonts, the Package for CD feature should have copied them. Check the package folder for a subfolder named after your presentation. All linked media should be there. If a video still does not play, the restricted PC may lack the required video codec. Convert the video to a widely compatible format like H.264 MP4 before packaging.

The slide show appears distorted on a high-DPI display

The PowerPoint Viewer may not scale correctly on high-resolution screens. The presentation might appear small or stretched. To fix this, right-click PPTVIEW.EXE, select Properties, go to the Compatibility tab, and check Override high DPI scaling behavior. Set the scaling to Application.

Item	Package for CD (with Viewer)	Export to Video (MP4)
Software required on target PC	None (Viewer included)	Built-in Windows Media Player or Edge
Interactivity	Full (clicks, animations, transitions)	None (plays like a movie)
File size	Large (includes Viewer + media)	Medium (compressed video)
Security policy bypass	May be blocked by AppLocker	Rarely blocked (video files are safe)
Best for	Presentations with animations and embedded media	Simple slide decks without interactive elements

You can now run a full PowerPoint slide show from a USB drive on a PC that blocks software installation. The Package for CD feature gives you a portable Viewer that works without admin rights. If the Viewer is blocked, use the video export option instead. For the most reliable playback, test your USB drive on the target PC before the actual presentation.
