I just realized we both stumbled upon the same workaround haha. Sorry for not reading the entire post. Also I ran the update.exe in the application directory and now 1.0.4 launches normally from the original shortcut.
Hi, I just wanted to let everyone know if you click on your iniManager shortcut, go to "properties" then click "open file location" and open the folder "app-1.0.3", within that folder there is a inimanager.exe that will launch properly. I'm sure the team is working on a fix, so this is a temporary workaround. You can also create a new shortcut by alt-clicking on the 1.0.3 inimanager.exe for the mean time.
