If You can't install MioPocket on your device because after clicking Run MioPocket it stops and nothing happens this is what you should do:
  1. Go to SDcard\MioAutoRun\Scripts

  2. Edit Unlock.mscr with notepad

  3. Find line containing If(WndExists("MainShell"))

  4. Comment whole IF block. That mean change this:

    If(WndExists("MainShell"))
    #Add message to log
    WriteFile(InstallLogFile, "Unlock.mscr: Hiding the main menu...^NL^", TRUE)

    Minimize("MainShell")
    Run(ProgramsFolder\"TroNik\WindowHide.exe", "MainShell")
    EndIf

    to this:

    #If(WndExists("MainShell"))
    # #Add message to log
    # WriteFile(InstallLogFile, "Unlock.mscr: Hiding the main menu...^NL^", TRUE)

    # Minimize("MainShell")
    # Run(ProgramsFolder\"TroNik\WindowHide.exe", "MainShell")
    #EndIf

  5. Repeat installation steps.

If problem still occurs you should see what's inside install log: \MioAutoRun\Backup\InstallLog.txt
