Gees, the program looks so simple when using. But I am having problems decoding a freebie file that is in RTE Format. Anyone can explain to me how to decode a RTE file? Pretty Please..

There should be a readme indicating what file is the seed file (what the file is encoded to).  There are a few decoders out there, here's a clip from Russel Cook's program readme. 

3.2 Decoding a file

• Make sure the "Decode" radio button is selected at the top of the dialog.
• Press the "File to Decode" button to select the RTE source file to decode.
• Press the "Key File" button to select the file to be used as a key in the
  decoding process.  This must be exactly the same file used to encode the
  source file.  If the file is different, you will be warned.  You will be
  prompted with the expected file name.
• Press the "Save As" button to select the output file name.  Once the file
  name is enetered, the conversion process happens immediately.  You will be
  notified of the success or failure of the conversion process.  You will be
  prompted with the original source file name that was encoded.

It's been a while since I've used anything else, each one should have a set of instructions.  It's relatively easy, but can be intimidating when you do it the first time.  

K..I am using the 2.0, and it didn't come with a readme, even in the freebie. All it is in the zipfile is just an exe file. I got it from the RTE website, download section.  I do not see 3.2 anywhere.

Trying to decode trekkiegrrrl's hamster from DAZ's house mouse. I keep getting a message.."Are you sure you want to replace........?" I already had to reinstall DAZ's house mouse. I am wrecking my obj files from trying to decode. :-( 

RTEncoder 2.0 is still only an alpha and non-functional (see -> http://www.rtencoder.com/).

You'll need to use 1.01 to be able to do anything.

Sorry, that isn't Version 3.2, it's from the readme.  I'm behind here, still using Version 1. 

Your best bet is to drop trekkiegrrrl an IM if you're having problems with the instructions.  I don't have her hamster or the housemouse.  Sorry I couldn't be of more help.

Finally got it done using 1.01. Thanks peeps. I hope I do not have to go through that again.

The first time is always the hardest.  Of course there are so few things encoded and the time between use always makes it seem like it's the first.

Glad you got it worked out!
