have you rights to read in the registry? with an administrative account i run safely your snippet (you need to add a newline after scalar(keys %$BaseKey) ):
Win32::TieRegistry=HASH(0x3b7e8c)
Number of subkeys found: 77

[long list of unistallable programs]

If you run 
  reg query HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersi
+on\Uninstall

[download]
in the command prompt you see some output?

you can also find interesting Win32::TieRegistry and Delimiter

UPDATE you need to recur to povershell to see security descriptors of registry keys: 

 powershell Get-Acl hklm:\SOFTWARE\Microsoft\Windows\CurrentVersion\Un
+install
