that resets the association for the .exe extension this is usually caused by a virus so make sure you do a fill system scan when you are finished

"I get a message saying that the Setup file is "not a valid Win32 application" when I try to install the Player. What can I do?

For some reason, the Setup file has become corrupted. You must delete the Setup file from your computer, and then download a new copy of the Setup file from the Windows Media Download Center. First, clear your browser's Internet cache by doing the following in Internet Explorer:
On the Tools menu, click Internet Options.
On the General tab, in the Temporary Internet files area, click the Delete Files button, and then click OK.

To obtain the complete Setup file, we recommend that you download it from the Windows Media Download Center to your desktop before you run it. To download and install the Player, do the following:
On the Download Center Web page, click the Download Now button for the Player version that you want.
In the File Download dialog box, click the Save button.
If you don't want to save the Setup file to your computer first, click the Run button instead. Setup will start automatically after the file is downloaded to your browser's Internet cache. We recommend that you do this only if you have a fast Internet connection, and you have cleared your browser's Internet cache first.
In the Save As dialog box, in the Save in box, click Desktop, and then click the Save button. A dialog box appears that shows the Setup file download progress.
After "Download Complete" is displayed, click the Run button in the dialog box to start Windows Media Player Setup."
