I'm trying to install Visual Studio 2017 Community because the last version i had, was a pre-Release of the same version. But now i can't keep using the program because it forces me to update to a new one.
I found this question with a similar problem but the answer didn't work for me. Any ideas?
TL;DR The problem can be in optimized (tweaked) system. Enable services that was originally on.
If you are sure that there is no any of internet / firewall issues, all updates are installed (to meet requirements, especially for .NET Framework), then you should check log file in %TEMP% directory.
A path something like C:\Users\<username>\AppData\Local\Temp\dd_bootstrapper_<date and time of last run>.log.
I'd expect, that it says:
Verifying signature
Caught Exception: Type = CryptographicException, Message = There are no more endpoints available from the endpoint mapper
The first step is to install the certificates.
If the error still there, then check system services (
+ R, type services.msc). Go through all list, read descriptions and search for certificates, private and public keys. I started CNG key isolation service (KeyIso) and magically the installer became normal.
Also I think this Uninstaller can be useful for everyone who did upgrade from previous version (2013, 2015) like me.
The log at %TEMP% showed a certificate problem .
Since the machine was an old windows 7, I had to update IE8 to IE11 so the installer could download. It wasn't installing yet. I had to set IE security level from medium-high to medium.
The log was:
VisualStudio Bootstrapper:7/15/2020 12:32:35 PM: Download failed using WebClient engine.
