Don't waste time repeating the same act many times. You should look to see what is wrong with what you have done and correct your mistake. If you do it correctly and it does not work, please provide evidence.
Why don't you tell us exactly what you do with details including Minecraft version, optifine version and filename and size, shadersmod version, filename and size, OS name, OS version, 32/64bit, Java version, what launcher are you using?
How have you install OptiFine? Does it work?
List folder 1.7.* in versions folder in minecraft folder.
Manual installation instruction is still in this thread. It is faster to navigate back several pages to find it than to rewrite it. It is not easier to do. Many people can't do it correctly.
Here is the link for 1.7.4.
If you are going to install the 1.7.5 version, just adapt the instruction.
Thankyou, i did the manual install and its all working good now
