Internal Error 2503/2502

[Im Batman]

Beautiful! My mind is a little blown, but this worked for me where the other suggestions did not. Thanks!

I have found that end task the explorer.exe and re-open with admin privilege to work but will reset if you reboot your computer. I found this solution when I had to install Microsoft Office and it worked perfectly.

Problem is in permissions on C:\Windows\Temp folder.

Somehow Administrators-Full Control (I'm member of Administrators group) is not enough.

Added permissions as <My User> - Change and thats it. Installer works as a charm.

Hope this will help somebody.

Solution for internal error 2503/2502 on windows 8 as follows

1. Goto TaskManager > Details > Explorer.exe & click on End Task.
2. Now Click on File in Task Manager > type Explorer.exe ( here is the trick ) Check the box below shows as ( Create this task with administrative privileges.)
3. Now install / Unistall this should work 100%.

Just gave this a try. Worked like charm on my Windows 8.1 Enterprise.

With respect to those that have previously answered this question, most of the methods that have been posted are simply workarounds. The actual solution has been posted but for those that may require additional assistance I have created a video guide to fixing this problem permanently. As a previous user has stated the problem is due to a permissions issue involving the temp folder inside your Windows directory.

In my video below I demonstrate a step-by-step guide to fixing this problem in under four minutes. After following this guide you will no longer experience Windows installer error codes 2502 & 2503
