can not install adobe air

Hello, unfortunately I can not complete the installation of adobe air. The error that is generated is this: There was an error while installing Adobe AIR. It is possible that you have not been authorized by the Administrator to perform the installation. Please contact the administrator.

In my computer there is only one administrator account.

I searched the log file and this is what was reported by it, can anyone help? Thanks!
