7+ Taskbar Tweaker tries to download the file http://rammichael.com/downloads/7tt_setup.exe. If that fails, the error message is shown. Please check whether the file can be downloaded on your computer - perhaps the link is blocked, or your proxy settings are not correct.

I tried it on a WIndows 10, and it worked as expected for me.

In general, it's weird that opening the tweaker's window fixes it for you, as it should have no effect beyond just showing the window.

So I can't answer your first question.

You can enable more features and check it. I need as much information as possible to be able to help you.

how would your (functional) icon get into the System Tray if launch at startup is disabled?

I wanted to make sure, as I didn't entirely understand your formulation (e.g. "7+ console", when you probably meant the main 7+ Taskbar Tweaker window).

Also, please check whether you're using an inside build of Windows 10. Insider builds are not supported by the tweaker.

Is it only the Remove Gap between items option, or does the issue apply for all of the options?

Please open Task Manager on the Startup tab, and verify that 7+ Taskbar Tweaker is set to run at startup, and it not disabled.

I have set combine to never again for cmd.exe and it still doesn't crash.

That's weird. This shouldn't change anything, especially if you restart your system. Check out the Windows 10 PC, and let me know whether you find a pattern, or a way to reproduce the issue.

Пока закрою. Если будет дополнительная информация, оставьте комментарий.

I tried reproducing the issue on another PC with Windows 7, but it doesn't crash for me. And unfortunately, the report is not very helpful, as the crash happens in the code of explorer, and not of the tweaker.

Please provide as much details as possible for reproducing the issue, including:

• The tweaker options, including advanced options.
• The system settings of the taskbar (taskbar right click -> settings).
• If possible, make a video of the issue.

Also, try turning things off and see whether it still crashes. For example, I see from the screenshot that you have lots of apps running - try it with only a single app, or two apps, etc., and see whether it crashes. Also, try to run the tweaker with all of the options off and see whether it crashes.

The fact that it crashed for you on two different PCs, while no other user reported about this issue, probably means that there's something in your configuration that causes it.

Also, you mentioned that the issue didn't happen with older versions of the tweaker. If you could track the version which introduced the issue, it can be helpful, too. Older versions can be found here:

I could not reproduce the problem on my laptop, Windows 10. I'll try later on a different computer.

Meanwhile, can you attach a crash report? You can use the following guide:
How do I find event logs when a program crashes?

That's because VMware uses thumbnail previews. There's nothing to decombine, as there's actually only one taskbar item.

You can turn the feature off, see this answer.

I'm not familiar with QQ, perhaps it offers an option, too.

tray_icons_padding is supported in Windows 10 since 7+ Taskbar Tweaker v5.2, but it's implemented differently.
