Fix Error Code 2503/2502 on Windows 8

I have decided to give Windows 8 a few more days of my life (before deciding if I am going back to Windows 7). So I am re-installing many of the programs that I used everyday on my Windows 7 setup. Some of them are giving me this - "Error code 2503" dialog box followed by one more with "Error code 2502" while installation.

It appears that these installation packages lack required permissions to access and deploy files  necessary files due to Windows 8's strict security model. Right-clicking the installer (MSI or EXE) and selecting "Run as Administrator" solves the issue.

Just realized that some of you might still be struggling to find the option "Run as Administrator" in the context menu. Try right-clicking on you MSI or EXE with the Shift button pressed (Shift+Right Click that is), you should have the option now.

The second option would be to search for the file through Window 8's unified start-button-search.
  1. Press the Windows key 
  2. Type part of the file name and navigate to the file
  3. Now press Ctrl+Shift+Enter
This will run your MSI or EXE as administrator. Cheers.
