When installing or updating our Windows app you may run into error 2502 or 2503. On this page we'll explain why this happens, and how to fix it.

### Why does it happen?

During the installation process our installer creates temporary files in a folder that is assigned for this purpose by Windows. When the creation of these files fails, error 2502 or 2503 pops up.

The folder for temporary files is usually found at **C:\Windows\Temp**, though it may be elsewhere if you installed Windows on a different drive or in a different folder. 

### How to fix it?

1. Navigate to **This PC** > **Local Disk (C:)** > **Windows** and locate the **Temp** folder.

If you make any changes, be sure to **Apply** and **OK** them.

After fixing the **Temp** folder, retry running our installer.
