Using Internet Explorer 4.x, Adobe Acrobat Reader Download of Large .pdf File Stops Before Completion

When you try to download an Adobe Acrobat Reader .pdf file that is larger than 4.5 megabytes (MB) in size, using Internet Explorer 4.x, you may find that the process stops and cannot be completed.

This behavior can occur because the Acrobat Reader plug-in controls the flow control for the data. After the size of the file passes 4.5 MB, the Acrobat Reader plug-in tries to download the file in 50-kilobyte (KB) segments. Each time a segment is completed, the plug-in restarts the download at the beginning of the total file instead at the end of the last segment. This causes the Adobe Acrobat Reader to hang, and the operation stops.

To work around this behavior, upgrade to the most recent version of Internet Explorer, and then try again to download the file.
