In my previous post I detailed the epic adventure of a normal user installing Paint.NET v3.xx on a "fresh" XP SP2 computer. I also said that I’ve made it a lot easier in Paint.NET v4. Let’s check it out:
Again, from the top, the user has excitedly downloaded the Paint.NET installer, and goes to double click on it …
The first thing we get is a dialog telling the user what’s going to be installed. Since this is a fresh XP SP2 box with no updates installed yet, they will need Windows Installer 3.1, .NET Framework 3.5 SP1, and of course Paint.NET. Compare this to the old dialog that tells the user what they need, and barely helps them to get it all.
Once the user clicks OK, the Windows Installer 3.1 package will be installed in automatic ("passive") mode. Installation will begin immediately, and the user will not need to click on any "Next" or "Finish" buttons. It will close once it’s done.
It installs fairly fast, and that’s good because most people will have no clue what any of the stuff on the dialog means.
Next, the .NET Client Profile package will also be installed in automatic ("passive") mode. Installation begins immediately — there’s no need to futz with buttons saying Accept, Next, or Finish, and it closes once it’s done.
This part can take awhile depending on your Internet connection, and I really wish they had a better UI to indicate this. The alternative is to add tens of megabytes to the download ZIP. I haven’t customized the graphics in the .NET Framework Client Profiler installer yet, but I plan to in order to make it more apparent that this is part of the Paint.NET install flow.
Finally, the Paint.NET v4 installer is launched! Ok, now the user finally has to worry about buttons saying Next, Accept, and Finish.
Note that the header graphics are just placeholders, I’m still figuring out what exactly I want there. I need a good "night" picture to put behind the white-text version of the logo 🙂
The installation progresses …
By the way, the "optimizing" portion of installation is much faster now with .NET 3.5 SP1 because of improvements to NGEN.
Once the user clicks "Finish" on the last page of the installer, they will be asked to reboot. This is because Windows Installer 3.1 requires it. (Remember, this blog post details installation on a "fresh" XP SP2 system! Most users will not have to worry about this rebooting nonsense.) I’ve written my install flow to only require a reboot at the very end of all the installations. Rebooting in the middle causes a lot of continuity problems and is a horrible user experience. Most systems won’t have to reboot though, as Microsoft has done a pretty good job of not requiring it for .NET itself. The v3.xx releases of Paint.NET actually cheat here and simply tell the user they should restart. Most people don’t see this, or ignore it, and it actually causes crashes and whatnot. So, yes, a new feature of Paint.NET v4: a reboot dialog! You heard it hear first! 🙂
And there you have it. Once the user has their hands on the Paint.NET v4 installer, that’s all they have to figure out. The rest is done for them. Once they restart, they’ve got Paint.NET installed. No ifs, ands, or buts. The barrier to entry for Paint.NET has been dramatically reduced.
So far the Paint.NET v4 download is about 3.7MB and includes Windows Installer 3.1, .NET Framework 3.5 SP1 Client Profile bootstrapper, Visual C++ 2008 SP1 runtimes (x86 and x64)*, the OpenMP redistributable (x86 and x64), and of course Paint.NET. I’ve done a lot of work and experimenting to figure out the best way to pack things together to get the smallest download possible — that 3.7MB actually expands to over 20MB in the temp directory!
Anyway that’s enough on the installer for now. My next chunk of work on Paint.NET v4 is in the guts of the rendering engine with the goal of dramatically reducing the memory footprint, and increasing rendering throughput on many-core (4x and up) systems.
* Version 3.xx uses the static versions of the runtime. Using the DLL version is preferred, for various reasons, and so I decided that Paint.NET v4 would finally switch to it.
