Hello Doctor. Some infos for your system's stats would be helpful  for a better answer. The cause is maybe your graphics card or something else. You can edit your post (options --> edit) if you wish. For now, try to download and install an older version of Viewer 2 and set your software updates NO to be installed automatically. (Preferences --> Setup --> Hardware). You can find older versions at the following link:

The older versions of V2 are still active on the production grid, but are not formally supported by Linden Lab Customer Support.

Good luck

EDIT: Please check out this.

Basically it could be 3 reasons:

1.) The file is currently being accessed by another process. Usually a restart should clear the lock on the file.

2.) Permission error. Access to c:\program files under Windows 7 is only possible with Administrator permissions. Maybe the installer didn't request Administrator permissions properly.

3.) Physical defect on the hard disc where the file is stored. Quick workaround would be to rename the file so a new copy will be written on a different physical location on your hard disc. If that is the case, you should consider running a full check of the disc with the tools of the hard disc manufacturer.
