How permissions affect installing the Shockwave Player with Windows NT, 2000 and XP?
If you don’t have administrator access to your Windows NT, 2000, or XP-equipped computer, you may not be able to install the Shockwave Player successfully. Permissions can be tricky, but, in general, you should be able to install and use the Shockwave player if your administrator gives you full access to the Macromedia directory : C:Winnt\System32\Macromedia\ for Win 2000 and NT, and C:\WINDOWS\system32\Macromed for XP.
