Recently while trying to install programs, I started getting the Error 2502 pop-up which was followed by Error 2503. The pop-up for Error 2503 followed Error 2502.

The problem occurs because of permission issues. In order to resolve the permission issues for Executable (.EXE) is –

  1. Right click on the Executable.
  2. Run as Administrator

Unfortunately, the program which I was trying to install had its installation files wrapped in a MSI installer. The problem was that on Right Clicking the executable, I did not find any option to run the file as Administrator. So, to resolve this, what I did was to put the MSI installer file in the C: drive and then launch the executable from a Command Prompt (CMD.exe) which had Administrator Privileges.

Hope this helps.
