How to fix this pr 24124r177y oblem
There is a program named Vm_sti.exe executed in the background. It creates a virtual application to receive the video stream from our device without notify to user so that any other applications executed by user can't get the preview image.
Because Vm_sti.exe is auto-execute after Windows
start, we must terminate the process before we modify it. Please press
Ctrl-Alt-Del to pop up the Windows task manager and switch to the page
'processes'. In the figure below, find Vm_sti.exe and press the button to
terminate it
Use Windows file manager to find %WINDIR%/vm_sti.exe.
(%WINDIR% is the directory that Windows installed)
Use the edit tool (for example, UltraEdit) to
open vm_sti.exe. Switch the operation mode to hex display. Find "76 00 69 00 64
00 5f 00 30 00 63 00 34 00 35 00"
Modify "76 00 69 00 64 00 5f 00 30 00 63 00 34
00 35 00" to "76 00 69 00 64 00 5f 00 30 00 61 00 63 00 38 00"
Repeat the procedure from step3 to 5 on another vm_sti.exe (the directory is C:\Program Files\Vimicro\VM301B\Driver AutoInstall\Driver Files\vm_sti.exe)
Restart Windows to activate the modification.
