Dropbox does NOT update its overlay handler dll but keeps that at a
constant version so it won't have to update.
So do other apps.
TSVN updates it's extension handler dll every time because it has to
(for reasons I'm not going into here).

> For this purpose I can't understand, why you don't use simple ShellExecute plus remembered list of apps and do the restart manually? Instead, you're talking about some restarting functionality, that should be embedded into applications being restarted. Is this another problem that comes out from MSI installer? Maybe considering some other solutions (InstallShield, Nullsoft) would be an option to solve this?

InstallShield uses msi as well.

Seriously? ShellExecute?
Please think long and hard before you go there further...

> No, I'm not getting this at all. If others shell extensions (like mentioned one: Dropbox, packers plus many more) can update DLLs and themselves without making such mess, then it lead us to the conclusion, that not shell update itself is a problem, but MSI installer. Why then don't get rid of them and try to use something else? Something that other shell extensions are using to carry their system-level updates?

As I said above: they don't update the extension dlls. And when they
do, they show the very same as TSVN or require a reboot.
Or don't require a reboot and hope for the best. I've seen all.

Now, please:
Either learn how installers work and why they work like this, or just
accept that you have to restart after upgrading TSVN. Either way, I
won't comment on this anymore.
