Roxen Challenger supports Windows NT 4 SP 3 and works as a development environment on Windows 95 and 98 as well.

Generally, Pike scripts and RXML code can be moved from Unix to Windows systems more or less directly, but there are a few details to keep in mind:

• File names. Unix uses a slash "/" to separate components in path names, while Windows uses backslash "\". However, internally Windows accepts "/" as a path separator. Unlike Unix paths on Windows are case insensitive. If a file index.html exists it is impossible to create a file Index.html. Windows also suffers from short file names, a file name can always be abbreviated to be 11 characters long. It is therefore often not possible to treat file names or paths as being unique on Windows, it is usually possible create another form of the file name or path that will be accepted.
• There are differences in terms of memory management, user identities, and file protections. While not generally a problem for the basic running of Challenger, security issues may need special attention.
