To avoid spaces problem in path name first checkout directory in quotes: cd "C:\Program Files\..."
then run just the execuable: start target.exe
.
Also run cmd without messages adding @echo off
.
@echo off
cd "C:\Program Files (x86)\RealTemp3.70"
start RealTempGT.exe
exit
Add .bat
file to directory that opens after running command shell:startup
.
