Cant install addons

Hi, my name is Luka i cant install any addons when i click install addon from file and select .py file nothing happens please help

What addons are you trying to install. Do they say they are compatible with the version of blender you are using ?

What version of blender are you using ?
What is your operating system ?
etc etc

Hi Luke, do you think you could answer a question that has this little information?

From the link it seems the script is for blender 2.49. This will never work in anything newer unless the author has updated it and said it works with your specific version of blender.
