Adobe Error 1303. The installer has insufficient privileges to access this directory: C:\Programs Files (x86)\Common Files\Adobe\ARM\1.0 when trying to update Adobe Reader 10.01 on a Windows 7, 64-bit machine. What I've found is that once I allow Adobe Updater to download updates, the 1.0 folder is created under ARM. As long as I don't start the update, I can access this folder. Once the update starts, if I try to access this folder I get an access denied message and the install fails with the Error 1303 message. I've tried making myself the Owner of the folder, tried running KB947821, have disabled the Firewall and shut off the UAC, none of which works. My guess is that there is a problem with the update itself changing the security.
Anyone have any other ideas beyond waiting for the next update, that will hopefully work better than this one?
