Sharpcompress write in Program Files folder

Question

I'm trying to write some files in my folder which's inside Program Files folder... I'm getting error "Access denied" every time I try to write them... I tried to open the .exe (which makes the extraction) in Administrator mode and change folder rights to "Everyone"/"All Rights" and I still got problem with permissions.

Code:

    Using archive As IArchive = ArchiveFactory.Open(PastaDownload & "\" & NomeRAR)
        For Each entry In archive.Entries
            If Not entry.IsDirectory Then
                entry.WriteToFile(PastaSistema, New ExtractionOptions With {.ExtractFullPath = True, .Overwrite = True})
            End If
        Next
    End Using
