Before proceedings with solutions, make sure that your system is compatible with Parsec.

Solution 1: Update Your Graphics Driver

Drivers are continuously updated to cater to new technology developments and patch known issues. If you are using an outdated version of the graphics driver, then Parsec may throw the error under discussion.

  1. Update your Windows OS by logging into an administrator account.
    Check for Updates in Windows Update
  2. Open the website of your graphics card manufacturer.
  3. Find drivers related to your graphics card.
  4. Download and install the newly updated driver.
  5. Then launch Parsec to check if it is working fine.
  6. If your system has integrated graphics cards, then update its driver as well.
  7. If you are using AMD APU, then lower the resolution of hosting settings to 1280×800 or lower (in Windows). Launch Parsec and check if it is working fine.

Solution 2: Roll Back Your Graphics Card Driver

Not everything that is updated is good, it can sometimes have its share of bugs. The same could be said for your graphics card driver. The Intel’s graphics card driver released in September 2019 has a bug that caused issues for Parsec which resulted in the error under discussion. In that case, rolling back your graphics card driver may solve the problem.

  1. Rollback your graphics driver to a previous version.
    Roll Back Driver
  2. Now, launch Parsec and check if it is working fine.

Solution 3: Disable Streaming Apps

The Parsec error 15000 could be caused by different streaming (or remote connection) related applications like NVIDIA Shadowplay, Game bar or TeamViewer, etc. In that case, disabling these applications may solve the issue.

Disable NVIDIA Share/Shadowplay

  1. Launch Nvidia GeForce Experience.
  2. Click on the General tab in the left pane of the window.
  3. Now in the right pane of the window, toggle off the switch of “Share”.
    Disable NVIDIA Share
  4. Exit the application after saving your changes.

Disable Xbox Game bar

  2. In the right pane of the window, toggle off the switch of the Game bar.
    Disabling Game Bar
  3. Now launch Parsec and check if it is clear of the error 15000.

If you are using any other streaming/remote connection applications, then disable them as well. You can also clean boot Windows to check if any other application is creating the issue.

If you are still having the issue, then try to delete the old machine and recreate a new one.
