I have downloaded Firefox 7.0.1 setup file. When I click on it, it starts extracting and then a pop up window appears asking whether to install as administrator or as current user. When I say as current user nothing will happen. I have not created an administrator account when I installed Windows 7 on my desktop. The only user account in my computer is with administrator rights. I haven't came across any issue like this before while installing any other software. I haven't had any other version of Firefox on my desktop before.
