Hi, Today I tried to install PTE 6.5.4 on my Windows XP Pro machine. I was running PTE 5.5 and then 6.0 (DeLuxe) before. The installation seemed to go OK but I can't launch it, nothing happens when clicking on the Desktop icon or even when clicking on PictureToExe.exe in the Programs folder. Any idea what the reason could be? PTE 6.0 or 5.5 still run fine. Christian
