Can't install Unity WebPlayer HELP !

Here's what happens when i try to install, I've tried it multiple times. First up is without running in administration. This is run with the browser opened, and not opened.

1)Error opening file for writing:

Unity\WebPlayer\UnityBugReporter.exe

Unity\WebPlayer\UnityWebPlayerUpdate.exe

Unity\WebPlayer\loader\UnityWebPluginAX.ocx

Unity\WebPlayer\loader\info.plist

Unity\WebPlayer\loader\npUnity3D32.dll

Click Abort to stop installation, Retry or try again, or Ignore to skip this file.

I clicked retry but doesn't work. (Clicked it multiple times.) I clicked ignore for each of the ones above, But didn't do me any good since i still couldn't run any unity games.

2)Second if i run it in administration Everything goes through, BUT it was quick, A little too quick. It looked like I didn't install anything. I still think it skipped the files below... This was installed with the browser opened, and not opened

Unity\WebPlayer\UnityBugReporter.exe

Unity\WebPlayer\UnityWebPlayerUpdate.exe

Unity\WebPlayer\loader\UnityWebPluginAX.ocx

Unity\WebPlayer\loader\info.plist

Unity\WebPlayer\loader\npUnity3D32.dll

Here's when i try and run a unity game

Error launching Unity Player click Error details or Install manually

clicking error details shows below. "Failed to load Unity dll".

Clicking install manually doesn't help since I've installed it already. Done it after I've removed Unity WebPlayer, and restarted my computer. After the restarted my computer I tried install manually but the output was the same as everything above.

Please help, And Please reply thank you.
