FileBot

I've installed Version 4.0 with the Nullsoft installer. At the end my Windows 7 system was
restartet without any question!!!!!!!!!!!!!!

WHAT'S THAT FOR A BULLLSHIT??????????

Fix this!!!!!!!!!!!!
Thats an outrageousness!!!!!!!!!!!

The NSIS installer does no such thing, nor the the MSI require Feel free to look at the code. According to that screen shot it is Windows Installer that initiates a reboot, so it's a bug in Windows Installer on your specific system.

Some people, at least say thank you for a great program, and ask first if the program does that nicely.

I can verify that using the Windows setup application on Windows 8 also resulted in an announced and unexpected system restart. I'm sure this is not a "a bug in Windows Installer on (my) specific system", but rather by design. While I don't feel anything near the disproportionate outrage as the op, it is still something that shouldn't happen. I would think that at the least there should be a warning beforehand, although it would be better if the triggering conditions were determined and managed better.

And, yes, FileBot is an outstanding application for which I am grateful! Thank you!

Does anybody have an idea why?

It's not happening on my system, and I'm specifically setting /norestart when calling msiexec. The NSIS installer is definitely not initiating a restart, it's the MSI installer which I can't control.

Can you reproduce that with every install? If it's reproducible I can try some things, otherwise can't do much about it.
