Hello..

When I run this script with the DLL included in the zip file

I do get the URL table displayed

other than that I get an error spammed a lot of times into my console. (CMD.exe)

Exception calling "Unprotect" with "3" argument(s): "The parameter is incorrect.
"
At C:\Users\Agam\Desktop\ExtractChromePasswords.ps1:39 char:5
+     $row | Add-Member -Name Password -MemberType NoteProperty -Value  ...
+     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], MethodInvocationException
    + FullyQualifiedErrorId : CryptographicException

Ill be ver happy if you explain to me what can I do in order to fix this problem and display the UserName and Password as expected!
