korell: The version 1 installers all had an integrity check, including those with only one exe and no bin files. I used to find that useful to check my installers were fine, especially the multi-part exe+bins installers.
Now that we have the v2 installers, they have digital signatures for the single exes and the multi-part exe+bins does still have an integrity check, but only on running the installation itself, so you can't run the check without clicking to install the game. I'd like to have the option to run the installer and just run the integrity check without installing the game.
But your method for downloading and then using the downloader to check the file is a definite possibility. Thing is, my slow net means I need the resume function for the large games. I could download the bin files one at a time, but then over the time it would take, and with GOG currently rolling out silent updates, I'm at risk of getting old and new files mixed up if they make a new release before I finish getting them all from the previous version. :(
yup i perfectly understand your problem , with the wifi , myself i have a slowest connection , however i don't use a wireless connection. But still time to time the browser failed to finish a downlaod . I must deal with , but i trust far more my browser than the downloader ....
i never ended up with a mixed files for a game so far, consider i have a slower connection then but with probably less timeout than you have.
try a bit my method , if not satisfy back to the downloader. i don't have other idea , except than the gog support would help us.... but i agree the shaddy updates are just disrecpectfull to us.and doesn't give a good impression.. :(
