stupid question #2:
Should we run the bat file again after install the update?
You shouldn't have to, I didn't on my test system and i logged in fine.
For those who are afraid of F'ing up their systems, wait until Pesty releases a more "user friendly" installer.
DH, the way your batch file works, you need to post that before installing the GW5 Update, they need to run the Restore OP + 4 bat file, and then install your update and use the GW 5 bat.... This will prevent the loss of the OP + shiplist and ftrlist.
That is Only with your installer..
With my installer, people only need to use the GW5_Uninstall.exe, then install the GW5_b_Installer.exe
It is almost finished being compiled and I will start upload as soon as it is done.
