5.5b install problem

Discontinued Software Weather Watcher - Support
1

Hello,

I cannot get the latest version 5.5b to upgrade. I receive an error message that states:

[b]C:\Program Files\Weather Watcher\dl.exe

An error occured will trying to replace the existing file:
DeleteFile failed: code 5.
Access is denied.

Click Retry to try again, Ignore to skip this file (not recommened), or Abort to cancel installation.

 <Abort> <Retry> <Ignore>[/b]

Any ideas?
