Try searching for the forum page and then install Forge. If your really stuck download WinRAR. And ModLoader. Download it. Click on it and chose open with WinRAR? And then drag it into .minecraft. ( Search for %appdata% on a windows computer.)
You can make an archive using winrar or other program. When you install winrar, you mark the files--> right butoon--> add to archive,and they`ll be ready :)
Because you have to use WinRAR to unzip it and install it.
1) find your .minecraft folder 2) open the .minecraft folder 3) open the bin folder 4) right click minecraft.jar (you will need winrar or 7zip etc) open with winrar or 7zip 5) follow instructions on how to install the mod.
You need to use winrar. Once you download your server it will go to winrar. Extract the server from winrar to desktop. Once you've did that you should be able to see Debbo v3.5 on your desktop right click on it and click run as administrator. ;) Should work. If it didn't work on winrar where it has debbo it has anti-virus install that and it should be 100% working.
No, there are other programs that can decompress minecraft.jar on the Internet. 7-zip is a program like winzip, but it's free.
WinRAR was created in 1995.
Download it off the minecraft forums. Then drag everything in the file into the minecraft jar on winrar, or 7zip.
rarlab.com is the website for the publisher of WinRAR.
