Code: -15000 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 If you are using an outdated version of the graphics driver, then Parsec may throw the error under discussion.
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.
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
Disable Xbox Game bar
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.
