Steam ? run as admin.

For the first error did you get the chance to click on "continue" ?

Taken from another forum..

Download and run http://www.microsoft.com/en-us/download/details.aspx?id=35 and wait for setup to finish. Reboot if asked.

Exit steam, make sure it is closed then right click the steam icon and select "Run as Administrator".

Verifying Arma2 free and Arma2 OA game cache. Wait for downloads to finish if necessary.

Start once Arma2 free and exit when done.

Start once Arma2 OA and exit when done.

Start Arma2 CO, hopefully it works.
