UltraVNC

Personally for me, the instructions on enabling gui 5(auto connect),

was not clear.

I have now figured it out and would like to share it, with my own understanding.

Locate the Build_exe.ini file
and make the following changes

change :
Application=scprompt.exe to Application=scprompt.exe -c 0 ...

Are you using "upx -9" ? I think that best setting is: "upx --lzma --best".

Is there option to connect to viewer just after launching exe (w/o options and info screen) ? You can use the count-down-timer, otherwise try: running the uvnc.exe with whatever arguments you want.
rename the build_7z ...
