Installer is very slow and causes the computer to become unresponsive

OS version: Win7 x64
ConEmu version: Every version I've tried in the last 6 months
Far version (if you are using Far Manager): Don't know what this is

*Bug description*
Every time I click "close and update" on the automatic update check, the installer
runs as it should, but it's extremely slow. The computer becomes unresponsive for up
to a few minutes, which isn't necessarily a huge deal, but it's also kind of ridiculous
for a terminal window to be that painful to install. Why does this program take so
long to install and how can it be improved? For reference, I've seen this behavior
on every computer on which I've installed ConEmu (approximately 10), all of which were
running Windows 7 Pro.

*Steps to reproduction*
1. Click update when the automatic update request pops up
2. Click close and update
3. Voila - a slow and/or unresponsive computer for sometimes several minutes

So what can I do? That is MSI! I can't manage Microsoft internals!

May be that is your antivirus software, math be something else.
Anyway, if you do not like MSI why you've chose it?

Switch updater style to 7z packages and enjoy.

However, it is interesting, what part of updating process takes the time?

I'm not talking about the initial install. I'm only talking about the autoupdate installer.
This isn't specifically an MSI installer or Win7 problem because it only happens with
ConEmu in my experience. I regularly release software using MSI and it never takes
anywhere close to as long as ConEmu to install even though the programs are usually
significantly bigger. There's something specific about ConEmu in terms of what it's
trying to do when it installs that's causing problems.

I don't have a virus scanner running and I don't know what you mean when you ask why
I've chosen to use MSI. I open ConEmu, it asks me to autoupdate, and I click yes. If
the autoupdate functionality behaves poorly, I would think the developer would want
to know about that.

You can choose to ignore this I guess, but it's repeatable on every computer I've tried
it on.

There is no difference between "initiall" install and "update" I believe. If both are
doing by MSI.
