Issue

When you double-click a file downloaded from the Adobe Web or FTP site, the system returns the message "[filename] is not a valid Win32 application."

Detail

The file was downloaded using Microsoft Internet Explorer in Windows 95, Windows 98, or Windows NT 4.0 or later.

The filename has an unexpected extension (e.g., *.exe instead of *.zip).

Solutions

Do one or more of the following:

Solution 1

Rename the downloaded file so that its filename extension matches the filename extension on the Web or FTP page from which it was downloaded.

Solution 2

Download the file using a different Web browser (e.g., Netscape Navigator).

Solution 3

Remove and then reinstall Internet Explorer, then redownload the file.

Additional Information

Internet Explorer uses the registry in Windows 95, Windows 98, or Windows NT 4.0 or later to determine what filename extension to use for downloaded files. If registry keys are damaged or missing, Internet Explorer may assign files an incorrect extension, which will prevent the system from opening them. Reinstalling Internet Explorer rewrites damaged or missing registry keys.

Windows hides registered file extensions by default. To enable Windows to show filename extensions:

1. In Windows Explorer, choose View > Options (Windows 95 or Windows NT) or View > Folder Options (Windows 98 or Windows 95 with Active Desktop), and then click the View tab.

2. Select Show All Files in the Hidden Files section or folder, deselect the option labeled, "Hide MS-DOS File Extensions for File Types that Are Registered" (Windows 95), or "Hide File Extensions for Known Files" (Windows 98, Windows NT 4.0, or Windows 95 with Active Desktop), and then click OK.
