I can't install extensions on Google Chrome. What to do?

On https://chrome.google.com/extensions I can click install but it won't do anything.

On https://chrome.google.com/webstore , the only time the 'install button' showed up I clicked and it said something about a javascript error. The next time I tried to go to another app, the button wasn't there at all.

Uninstall Chrome and any and all instances of Java from your computer.

Run a registry cleaner like CClean followed up with a temp file cleaner like Cleanup (both available from Download.com)

Reinstall Chrome and then reinstall the most recent Java.
