What is file premissions?

Question

For years I've had the Webshots program on my computers. Recently I noticed that the photo manager part of the program was no longer operating. I uninstalled WEBSHOTS using ADD/REMOVE in Control Panel and I went through the contents of my hard drive and removed all traces, that I could find, of that program. I also looked at the registry using REGEDIT. Webshots is listed there but I was afraid to remove WEBSHOTS from the listings.

Then I started all over again: I downloaded the WEBSHOTS desktop. Then ran Install but I got the following message:

File Locked The file "C:|WINDOWS\webshots.scr" is locked and can't be overwritten by the install program. Press OK to cancel the install, reboot and try again.

I did cancel the install, rebooted and tried again and got the same result.

I am able to download the photos from the website but the manager willnot work.

So---what does the File Locked message mean?

How can I find what causes the lockup?

Should I have removed the program from the Registry listings?

Is there a way that I can solve this problem?

Thanks.

Permission Description

Traverse Folder/Execute File For folders: Traverse Folder allows or denies moving through folders to reach other files or folders, even if the user has no permissions for the traversed folders (applies to folders only) Traverse folder takes effect only when the group or user is not granted the Bypass traverse checking user right in the Group Policy snap-in (By default, the Everyone group is given the Bypass traverse checking user right.)

For files: Execute File allows or denies running program files (applies to files only).

Setting the Traverse Folder permission on a folder does not automatically set the Execute File permission on all files within that folder.
