I thought that the problem originated in having some remains from previous VS editions. I could not uninstall namely ASP.NET and Web Tools 2013.1. I have finally removed it after all by reinstalling VS 2015 and using the FixIt tool from this answer.. But still AspNetDiagnosticPack.msi fails the same way.
I also tried to uninstall the web development role completely, since I will probably not use it soon, but installation allways fails. Is there any workaround to make the VS installer work again?
The msi log is here.

But the problem is within custom action WebConfigInitialize and the log is no big help. I have observed that there was an entry Microsoft ASP.NET and Web Tools 2015.1 - Visual Studio 2015 when I ran the uninstaller tool - and this entry failed uninstalling. Perhaps the origin of my problems is that I once installed some beta verison of ASP.NET with Visual Studio 2015. I do not need ASP.NET for now, but I the VS 2017 installer is stuck on the error.
I have found WebToolsExtensionsVS14_rc2_48.msi in cached packages on my computer and uninstalling this package fails the same way with 1603 as the 2017 current package.

Similar problem here, that one ended with reninstalling his machine.
Or is there some tool that would show the dependencies of a particular MSI package?
The Developer's community link that is current and relevant to the problem is here.
It says:
We have fixed the problem in an upcoming release. We've addressed the
managed custom action in the ASP.NET Diagnostic Pack that modifies the
root web.config file to use a native code action. This should avoid
the CLR errors previously reported when it tried to launch the managed
code DLL during the install.
The fix for this is now in our latest Visual Studio Preview release.
If you'd like to try out the fix, you can access the preview build
here: https://www.visualstudio.com/vs/preview
Looks like there is no workaround except waiting for Microsoft's fix to that faliling custom action. I have ignored this recommendation at first because I did not check the date of comments properly but they are only one month old.
But when I have tried to install the preview it ended with exactly the same error.
In 15.7.1 version the same error again.

Answer 1

UPDATE: It looks like the issue might be a managed code custom action failing in the MSI in question (.NET code that can't run - for whatever reason 1, 2, 3).
Suggestion
I would first try to 1) do the reboot I recommend below - to clear the air and release any locks - then 2) disable security software / anti-virus and 3) try the install and enable logging as described below.
Core Deployment Problems
As deployment goes, problems tend to center around: 1) something is locked (in use - by other processes or other users logged on), 2) something is blocked (access / permissions denied), 3) dependencies are missing for your custom actions or the whole installer (runtime requirements not satisfied - for example missing .NET runtime version), 4) something is corrupted (data file, OS settings, malware is often the culprit here - or unwise tinkering), 5) there is an unexpected system state such as the disk being full, or more exotic the date and time is wrong, or there is a licensing issue or some other oddity, etc...
That is a very simplified list of causes - there are obviously many further issues, for example 6) localization errors: hard coded paths, erroneous parsing of dates and time, invalid characters in path names, etc... 7) file and path names are too long, 8) and the Microsoft specialty: weird and unexpected incompatibilities between products not thought to have a valid reason to conflict with each other (different versions of Visual Studio, etc...), etc..., but that is going way too far for your problem. Still, here is a generic "deployment problems" summary from some time back - just for reference.
Procedure
Reboot: The first thing I would do is to reboot and then try to invoke the install the regular way. This is just to rule out this "simple solution" (which sometimes works). There could be files in use that the installer must replace in order to complete.
Logging: In order to maximize the available debugging information you could log the install with verbose logging and debugging information (if you have access to the MSI itself).
Open an elevated command prompt (right click and run as administrator)
Change current directory (cd) until you get to: C:\ProgramData\Microsoft\VisualStudio\Packages\Microsoft.VisualStudio.AspNetDiagnosticPack.Msi,version=15.0.40314.0\
MSI Log: Run this command (adjusting paths as appropriate - especially for the log file): msiexec.exe /i AspNetDiagnosticPack.msi /L*vx C:\Test.log
Enable All: You can enable logging for all MSI files (slows installs, but great for advanced users): http://www.installsite.org/pages/en/msifaq/a/1022.htm (section: "Globally for all setups on a machine")
Interpret: How to interpret an MSI log file: http://www.installsite.org/pages/en/msifaq/a/1045.htm
Event Log: You can also have a look in the event log. Rather than repeating the procedure here, I will link to a similar, recent answer.
Different User: This is unusual advice (and I haven't tried it), but sometimes you can succeed with difficult installs by creating a new local admin user on the machine, and then running the installer from there. It has to do with errors in the user profile. Not the first thing to try, but adding it as an option.

Answer 2

I tried to uninstall VS 2019(!) and I faced the same problem (I cannot add or remove any component using VS installer).
It hang for a long time and finally throwed an error at "AspNetDiagnosticPack.msi".
I found a solution that led me also to
%programdata%Microsoft\VisualStudio\Packages\Microsoft.VisualStudio.AspNetDiagnosticPack.Msi,version=16.3.283.64955
I simply ran the msi stand alone. During the process I was asked to do kind of clean up for an outstanding installation issue.
After that I ran the uninstall ( And later the reinstallation ) of VS 2019 again and it worked.
Maybe this solution helps you along with VS 2017
