Description
I tried running rustup update today and it failed to update rust-std-i686-pc-windows-gnu:

I could solve it by deleting both

Thanks for the report @rnestler. I have no idea what's going on here offhand, but I'm sorry your toolchains got hosed.
lamarqua commentedon Mar 17, 2017
I've been getting this error consistently for a few months. Usually the toolchain updates just fine (that is, it seems to be functional), but I'm always getting the error messages. e.g.:
(The update failure may have been due to my internet connection, which sometimes corrupts downloads.)

@rnestler
This looks like an antivirus issue - something is removing the DLLs which rustup installs. This causes it to fail when it tries to update (by first removing the previous version) and also causes nightly to fail to start (missing DLL).
If possible, my personal recommendation would be to only use microsoft security products. If that's not possible, see if you can adjust the settings to allow rustup to work correctly.
@lamarqua That looks like a different problem. Are you installing 64-bit rust on a 32-bit system? It could appear to be working if you have a 32-bit version of rust earlier on your PATH.
lamarqua commentedon Mar 17, 2017
Nope, I'm running 64-bits windows 7 pro. I don't even think I've ever had a 32-bits rust version installed on this machine. (A search for rustc.exe on my machine gives none other than the stable / beta / nightly triad installed via rustup.)
I re-ran
rustup updateafter the failure, but this time, after having ranVsDevCmd.bat(which is basically the equivalent ofvcvarsall.bat, but for the new Visual Studio 2017 which I've been using):I didn't get any error message.
Diggsey commentedon Mar 17, 2017
@lamarqua Ah yes, rust doesn't automatically detect Visual Studio 2017 yet, so you need to run
vcvarsall.bat. This is a rust issue, but I suspect @retep998 is already working on this...It's surprising that
rustc --version(the command rustup runs) crashes though.lamarqua commentedon Mar 18, 2017
Yeah, it's weird, because it doesn't crash when I run it from the command line, even when I don't run vcvarsall.
It only ever crashes (showing a MessageBox) when I run
rustup update.Diggsey commentedon May 3, 2017
I'm closing this (the missing DLL issue) because if, as I suspect, it's caused by a virus scanner deleting DLLs, there is nothing we can really do about it.
@lamarqua If you are still having problems please open a separate issue.
