You have windows 7 or Vista?... Try to start it (Chrome and the .exe file) using right click, then Run as Administrator. Or you have XP?... Then you need to logon as an admin account or simply select Run As: Administrator. Or, if you do start -> Run -> type this "control userpasswords2" -> there you can make an account administrator. Or you can do all this in Safe Mode (press F8 when your Windows starts and choose Safe Mode, but this is your last option :) ).

Check if the current logged in user.. is added under the local administrator group. Right click on My Computer -> Manage -> Users and Groups->Groups->Adminstrator-> Make sure if the current logged in user name is there, if not please add.

Check your user account on your pc to make sure you have full Administrative access to do driver upgrades. Some drivers only allow the ADMIN account access to make changes. You might need to log in as ADMIN. Hope this helps.

It seems the file you are trying to open have incompatible formats. If the file is compressed you need to have a file to decompressed the file first like winrar archiver.

That means you don`t have the authorization to download the file. get the authorization to download the file and also check if you have the right download link to download the file.

When it says that that means that you are not the administrator of that computer get the admin to download it on their account.
