Erm, and what exactly? Your post makes no sense since you did not tell us for what program or from which location you attempt to download/ install or whatever....
When filling out a form on-line, it asks that you down load the Font package when you attempt to type. I have had the same error codes on other downloads since installing Windows 8. This happened to be an Adobe PDF in Adobe reader.
Moving this discussion to the Adobe Reader forum.
Google for error 2503 OR 2502 windows 8, and you will find tons of results. This seems to be a common experience on Windows 8.
The most common solutions in these results are
- run the installer As Administrator
- run the System File checker: sfc /scannow
- create a new user profile
Thanks for your replies. I was on the phone with Microsoft for a couple of hours today and they checked many areas and ran the system scan twice, Unable to resolve. They kicked it up a layer and will call back.
