Just put updater.bat into whatever folder you're going to be keeping it in, copy its location from the Windows Explorer bar and put it in quotes in the Target field. So if updater.bat is forever going to reside on your desktop, the location you've got is correct. The "Start In" field should show the folder location (so "C:\Users\User\Desktop" in this case.)
If you're sticking updater.bat in a different folder--say, C:\Program Files (x86)\AwesomeMod Updater for example--you'd put "C:\Program Files (x86)\AwesomeMod Updater\updater.bat" in the Target field and "C:\Program Files\AwesomeMod Updater" in the Start In field.
If you're sticking updater.bat in a different folder--say, C:\Program Files (x86)\AwesomeMod Updater for example--you'd put "C:\Program Files (x86)\AwesomeMod Updater\updater.bat" in the Target field and "C:\Program Files\AwesomeMod Updater" in the Start In field.
Thank you! I wasn't sure what the difference was between the "Start In" and "Target" fields. I tried quotes but I guess I must have gotten something wrong along the way. Much appreciated, Ambular.
One more question, if you don't mind: Does doing this run updater.bat and then TS3EP09.exe afterward? That would be the gist I got from reading this thread; that it would run one and then the other in succession after checking for updates. If there not a way to do this, then I'm assuming I'll have to run them separately. I thought there was because I thought I remembered doing something similar in another game years ago.
