For Windows XP Professional:
Check the permissions set for the Steam folder by following these directions:

2. Click Start, go to Control Panel and double-click Folder Options
3. In Folder Options, click the View tab
4. Scroll down to the bottom of the list and un-check Use simple file sharing
5. Close Folder Options
You can close the control panel and then navigate to the directory where you have Steam installed (by default it is C:\Program Files\Steam). Once you've located the Steam folder, follow these directions:
1. Right-click on the Steam folder, select Sharing & Security and then click the Security tab
2. Select Users under Group or user names and check the Allow Full control box
3. Click Apply and then click Ok
4. Log out of Windows and then log back in to the normal account (if it is not an administrator account)
