Sometimes you might get 2502 or 2503 errors while installing AirServer . The root cause of 2502 and 2503 errors is the MSI installation service on Windows.

Whenever you install or uninstall a program, files have to be written to a temporary folder. If Windows is unable to write to that folder then you get those errors. 

Solution

1. Go to Local Disc (C:) and open the Windows folder.

2. Find the Temp folder and right-click on it.

3. Go to Properties >>> Security tab >>> Advanced.

4. Click on your Windows user and change the permission to Full control.

5. Click Apply.

6. If you receive warning messages, click Yes and continue.
