Hello, i am having trouble downloading this. I click download and then once it has finished it wont open for some reason, so i tried to open it with jagex launcher but now everytime i download it, it opens with jagex launcher and it wont work, help please.

open with "jagex launcher" ? dafuq is that? anyway...

 

it has to open with java(do not change anything with "Open with..." , just leave it 

 

1. Open Default Programs by clicking the Start button, and then clicking Default Programs. 

2. Click Associate a file type or protocol with a program.

3. Click the file type or protocol that you want the program to act as the default for.

4. Click Change program.

5. Click the program that you want to use as the default for the file type you selected, or click the arrow next to Other Programs to show additional programs. (If you don't see Other Programs, or your program is not listed, click Browse to find the program you want to use, and then click Open. If no other programs are installed that are able to open the file type or protocol, your choices will be limited.)

OSBot is not associated with Jagex, you need Java to run the client. You can download that from java.com ^_^
