How to fix WINDOWS 2502&2503 error.

If you are a Windows user then you would know about the errors and error codes. Yes, there are lots of error codes but one thing is good in this case that Microsoft has many good engineers and also because of the active Microsoft Community, these errors can be fixed easily. All you need to just google whatever error code you are getting.

A few days ago, I was facing an error of 2502 and 2503. I don’t know how this error came in my PC but as I do lots of experiments like changing Administration Permissions, etc so this error started from there. Moreover, errors in Windows is fine, we will never get rid of that.

Why the 2502 and 2503 Error Occurs?

“The root of the 2502/2503 errors are from the MSI installation service on Windows. Whenever you uninstall or install a program, files have to be written to a temporary folder. If Windows is unable to write to that folder then the 2502 and 2503 are typically what you are going to get”. 

“The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2502”.
“The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2503”

So how to fix the issue permission error.

There are a few simple steps you have to do. Let’s dig into that.

  1. Go to “This PC”.

2. Open the “C” drive and navigate to the “Temp” folder.

3. Now Right-click on it and select “Prosperities”.

4. And the Go-to “Security” TAB.

5. Now select “Administrators” and click on “Edit”.

6. And make sure the “Full control” is allowed. If it’s not allowed just click on allow and save changes.

now you are ready to install any apps and you will not get the 2502-03 error.

many cases or other PC I found that this error was still occurring even after doing the above steps. So here you have to allow full control of all the users’ “systems”, “users” or “Authenticated Users”. And you will not get the error next time.
