If you consider yourself such an expert, you should be able to follow the translate5 Linux installation manual and "translate" it yourself to an windows environment. Instead of using the install-and-update.sh-script as described for Linux, you should be able to use the install-and-update.bat to install translate5 on windows, if you do it the right way.
If you call install-and-update.bat the first time, it creates a config file "windows-installer-config.ini" and stops execution. Please check the config file, if stored path to php.exe and mysql.exe are correct.
Just call the batch file again if you have checked / corrected the config file.
Please let us know your experiences and contribute to this manual!
