Traditionally, on the Internet, file transfers have taken place in one of two modes: text or binary. "Text" was implemented to be able to convert between the different end-of-line markers which are common with different operating systems. For example, Unix uses a single ASCII 10 character to terminate a line, while DOS, Windows, and OS/2 use two ASCII bytes with 10 and 13.
Downloading a binary file, such as a WarpIN archive, in text mode causes the file to become corrupt because it's usually not a good idea to add or remove bytes from binary files. So if WarpIN refuses to install an archive which you have downloaded from the Internet, this might be the reason.
Until we have figured out a better solution, do the following:
You can also use the "Wizilla" utility which comes with WarpIN until we have found a better solution for this problem. This adds a helper to the Netscape applications list to make sure .WPI files will always be transferred in binary mode.
With the Apache server software, create a file named .htaccess
(no typo, mind the dot in the front -- that's Unix-speak) in the source download
directory (where the .WPI files are) and place this line inside it:
AddType application/octet-stream .wpi
That should do.
