How to troubleshoot Zoom Share Screen not working?

What if the Zoom screen share is not working when trying to make a video call? Well, you’re not the only one having a bad day!

This year didn’t turn out as many expected. With the pandemic, we’ve seen lockdowns, businesses shutting down, and others shifting to remote working and telecommuting. The one thing that has kept businesses and families going? Online meetings. Zoom, in particular, has made it easy for people to connect from all over the world.

Thanks to its screen sharing capabilities, coworkers, clients, and bosses can easily collaborate with each other to check the progress of their projects. This allows for accuracy and efficiency.

But, like most software, Zoom has its share of bugs. One that’s particularly troublesome is the error code 105035 when trying to share the screen. The error, which reads in full: “Screen sharing has failed to start. Please try later. Error Code: 105035”, prevents participants from sharing their work.

Luckily, this error is fixable. Below we’ve gathered a few workarounds that you can try to fix ‘Zoom screen sharing not working’ issues on your Windows PC.

What Is Error Code 105035 in Windows 10?

The error code 105035 appears when Zoom’s screen sharing feature fails to work. Participants in your video call can only see a blank screen when you’re trying to present your projects on the other end.

At other times, during Zoom screen sharing, the audio goes mute, and no one can hear what you’re saying.

  • This error could be driver-related. You see, when your graphics driver is not functioning as required, the relay of information between the system and the corresponding hardware or software is severed. This could be caused by corrupted, missing, or outdated drivers.
  • The error could also be triggered by misconfigured settings in Zoom.

How to Fix “Zoom Screen Sharing Not Working” Issues

It goes without saying that to enjoy smooth Zoom calls, you need to have a solid internet connection. Video calls can take up a lot of bandwidth, and if you’re on a limited or unstable network, you might have some issues.

Solution 1: Reconfigure Zoom Settings

If you’ve improperly configured Zoom settings, you might run into the “Zoom Share Screen not working” issue. To fix this, try to adjust Zoom settings.

  3. Click on the gear icon in the upper right corner to open Zoom Settings.
  4. On the left pane, click on the Share Screen tab and check the “Enable the remote control of all applications” checkbox on the right pane. If this option is grayed out, exit Zoom, right-click its icon on your desktop, and select “Run as administrator”. You should now be able to enable this option.
  5. Still on the Settings window, click on the Advanced option at the bottom of the page to display additional settings.
  6. Check the “Limit your screen share to (_) frames-per-second” checkbox and input a value below 10 from the dropdown list.

Try to initiate the Zoom Share Screen again to see if it works. If you’re still getting the error, try the next fix below.

Solution 2: Change the Preferred Graphics Processor

If you’re using a laptop, automatic switching between GPUs is turned on by default to extend battery life. However, it could the culprit behind the “Zoom Share Screen not working” issue. Several users reported that disabling this setting resolved the error.

To try it out; follow these steps:

  1. Press the Win + S key combination, type in “NVIDIA Control Panel” (without quotes), and hit the Enter key. Alternatively, right-click on an empty space on your desktop and select “NVIDIA Control Panel”.
  2. Once the NVIDIA Control Panel window opens, click on the Manage 3D settings link in the left pane.
  3. Switch to the Programs Settings tab under the “I would like to use the following 3D setting:” section, and select Add.
  4. Click on the Browse button near the bottom of the page, and navigate to Zoom’s installation directory, which by default, should in C:/> Users> USERNAME> AppData> Roaming.
  5. Once there, locate the Zoom > bin folder, select exe and click on Open. Or, simply double-click on the CptHost.exe executable to add the file.
  6. You’ll be taken back to the Manage 3D Settings section, and the file you just selected should be displayed under “Select a program to customize:”.
  7. Under the “Select the preferred graphics processor for the program:” dropdown menu, choose “Integrated graphics”.
  8. Click Apply to save your changes and close all open windows.
  9. Restart your Windows PC and check if modifying the graphics settings worked to resolve the Zoom Share Screen error code 105035.

Solution 3: Update Your Graphics Driver

For you to make video calls, your graphics driver should be up to date and free of errors. If you keep getting the black screen display, it’s probably because your graphics driver is outdated or damaged. The best way out is to update it.

For people who know their way around computers, you can try to manually install the latest driver version for your graphics driver. To do so, you’ll need to find and download the appropriate driver version from your GPU manufacturer’s website. While this might sound easy, you must be careful not to download the wrong driver model and version. Otherwise, you risk running into compatibility issues.

But there’s a better, safer way to do this – using a reliable third-party program like Auslogics Driver Updater. This program will automatically detect your OS and all the device drivers installed on your PC. After running the diagnostics, Driver Updater will display the details of the drivers, showing you the ones that are outdated or missing.

It does all the hard work for you, so you don’t need to worry about searching for drivers that are compatible with your system. Plus, you don’t have to stress about installing the wrong drivers. The tool works with precision and accuracy to ensure that only the latest, official drivers are installed.

With the free version, your options are limited – you can only update a driver after a certain time period elapses. To enjoy all the benefits, opt for the Pro version. In both versions, you can schedule automatic maintenance to keep the device drivers up-to-date, and you can back up and restore your drivers as you wish.

Solution 4: Enable App Permissions in Windows

Have you confirmed if you’ve allowed the Zoom app to access your camera or microphone? It could be the source of your problem. The Zoom screen sharing feature depends on other components and resources on your Windows system to function correctly.

To verify these settings, follow the steps below:

  1. Open the Windows Settings using the Win + I shortcut keys.
  2. Select Privacy and scroll down to find the Camera setting under “App permissions” on the left pane.
  3. Be sure the “Allow access to the camera on this device” and “Allow apps to access your camera” options are turned on.
  4. Additionally, check if the “Allow desktop apps to access your camera” option is turned on and that Zoom Meetings appears under this section.
  5. Repeat the same steps with all the necessary permissions, like Microphone.

Solution 5: Reinstall Zoom

You’ve probably tried this option already. But, if you haven’t, let us guide you:

  1. Close the Zoom application and exit the program from the system tray.
  2. Use the Win + Q key combination to bring up the search bar, type in “Control Panel” (without quotes), and press Enter.
  3. Click on the “Uninstall a program” link under Programs and locate the Zoom application in the list of installed programs and features.
  4. Once you find the app, right-click on it, and select Uninstall.
  5. Follow the instructions on the screen to complete the uninstallation process.
  6. After you’re done, open your browser and go to the official Zoom download page to get a fresh copy of the Zoom app.

After installing Zoom, the Screen Sharing feature should function as required.
