Gerson, I am so grateful that I am a Mac user who, in my Windows virtual machines, never got beyond XP and never needed to. Once I got the proper USB-Serial adapter from Eric, I have had nothing but smooth sailing with flashing using MySamba.
Alas, Pascal's tool is another matter. Even though serial communications via the Mac Qt emulator work beautifully, I gave up weeks ago trying to get the Qt flash tool to work. I may revisit it one day, but I am not going to invest the time until I start hearing from more Mac and Linux users who claim success. Right now I am just gobbling up batteries.
So sorry to hear that flashing doesn't go so effortlessly for those using Vista or 7. If I encountered such headaches early on, I likely never would've have gotten involved in WP34S. Now, despite a banker's box of calcs--including a much anticipated yet now barely used 15C LE--the 34S is about all I bother with. I say this because it is true, but also to vex those who have complained of the the "utter domination" of the group by the 34S ;) Next, the Sudetenland!
Les
