"A Setup Package is either missing or damaged" error while installing Visual Studio 2015 on Windows 10

Just to say, it's now August 2016, and this problem is still alive and kicking (it wasn't just a problem with one specific build of VS2015).

For me, I ended up having to install VS2015 on a train, and using up my entire mobile phone's 2Gb monthly data allowance, as although it claimed only one package was corrupted, it ended up re-acquiring everything.

Oh, and then it got stuck whilst trying to install the packages. Giving up on the install, and rebooting my laptop actually got it started again.

So, short answer: the VS2015 installer still isn't particularly stable.

I had the same problem with installing VS 2015 Community. In my case the solution was to download the offline installer (ISO image, ~3,7 GB), mount the image and run vs_community.exe with administrative rights.

This was a problem with Visual Studio's web installer between mid-afternoon PST of Sep 4th through 11:30am on Sep 8th (also PST) which has now been fixed on our end.

Specifically, we were running a clean-up script on past pre-release web-installers for Visual Studio, but the script got too aggressive and deleted vcredist_x86.exe even though the RTM product still needed that particular package. Once we realized the error, we re-published and re-mapped that package so that web installs should now work correctly.

The other workarounds (download the ISO + install vcredist_x86.exe manually) should still be fine answers, but anybody else reading this now shouldn't need to worry about those workarounds.

And last, we're examining our internal policies and procedures to try and avoid this kind of broad mistake in the future.
