What follows are links to a stand-alone Windows program I wrote that takes a jumbled 5 or 6 letter word and shows the unjumbled english words that may be the source.  This is legitimate software and it is free of malware.  Still you install it at your own risk. It works by doing a brute force permutation analysis with a dictionary lookup to determine possible solutions.

Option 1:  Download Version 1 (no prerequisites) Unjumbler Click Here

(download option 2 requires registration/login)

Option 2:  Download .NET 2.0 Version Unjumbler Click Here

This (option 2) .NET 2.0 program requires that the Microsoft .NET 2.0 framework be loaded on your machine.  (Vista should already have this by default) If you do not know if the .NET 2.0 framework is on your machine, the program will tell you if the framework is absent.  This framework is rather large and may take 10 or more minutes to install. It can be downloaded from microsoft here.     Microsoft .NET 2.0 Download Link

After it is installed the Windows update mechanism will try to download and install an update to this Microsoft software (with the .Net 2.0 SP1 update).  This will take a while too, but it is a little smaller than the base .NET software. You may wait for windows to tell you that you  need to download the update or download it via this link and install it on your own.   Microsoft .NET 2.0 SP1 Download Link

Install this and any Microsoft or other software at your own risk.

This Unjumbler program is not warranted for usefulness or correctness. This is unsupported software.  Do not re-distribute.
