Need help badly please, About windows 7 starter

Hello!
Well, I purchased an Acer Aspire One that has Windows 7 starter on it,
From all that I had read before I purchased it I didn't see any of the problems I'm having so I have no clue as what to do.
I have an administrator account on it, everything seems to be like it should. .
But I tried to download flashplayer into a file of a browser I use instead of enternet explorer (As enternet explorer has totaled some of my past computers. . )
but it said, I could not save the file there, as to ask Admin to do so.
. . .
Also another completely annoying factor, the mouse auto clicks on everything if held on a link past, say what. . 2 seconds? At the most? I can't find anywhere to change this.
I've gone through over and over, and still can't find the problem, I'm an admin on it. . Why won't it let me do admin stuff?

PLeaase help me, I've own many desktops in my life and now that I work, and travel alot I wanted just a simple little laptop and the acer one had simply sounded perfect from my research,
but It's annoying the snot outta me and won't let me do what I would think be completely normal things.
Please help

Thanks in advance!

Edit: No ones replyin, so If no can help me change this, I understand. . But if you can at least tell me if it's fixable or not would be helpful so I'd know to return it or not.

For your clicking needs please go to Start - Control Panel - Folder options and check General tab under Click items as follows or try touchpad setting as BTNH108464 suggested.

Regarding Admin/ downloading issue, please specify where are you trying to save that file?
Is it possibly to select open files instead saving when browser prompts for download?

Also, please go to Start - Control panel - User Accounts and check that under your account is written Administrator and it is Password protected.
