I can look into whether there is a way. This mechanism is managed by the launcher code, which isn't java and isn't developed by us. It's developed by AdvancedInstaller.com
Technical stuff: I don't know their product, but I have anyway found
this page on StackOverflow, particularly the 2nd paragraph, which might be relevant to solve this problem. I hope this can help...

I'll see what can be done. I couldn't follow those seemingly clear instructions. Perhaps they were valid for another version of AdvancedInstaller? I'm checking with their team now.
