The nightmare hit me hard…
First I was unable to register ‘free’ ‘community’ edition – with error
we could not download a licence. please check your network connection or proxy settings.
After countless reinstalls from 2 different web installers provided on microsoft pages (sic!) and even installing it from iso image. I narrow the problem to be in wrong delegation setting in AD which end up being SAMBA4 bug and upgrade did help – The registration error message didn’t help with this, only adding “new account” yield at me about wrong delegation.
After successful registration and unlocking community version after 30days of trial use I hit another problem probably because I deleted one reg more than I should and installer was dumb enough to not recreate it (they need to improve installer or stop hide options in it)
'Code analysis package' package did not load correctly. - and - Project <name> could not be opened because the Microsoft Visual C# 2015 compiler could not be created. Please reinstall Visual Studio
I reinstall VS2015 more than few times even changing path, cleaning folder, regs. I end up digging thru forums/support pages to find those tips:
To uninstall the visual studio totally, we could try to use /uninstall /force command, it will remove the shared components, please take the following steps:
- Run installer (.exe) with /uninstall /force – those will clean alot more, first time I uninstall VS cleaner app found 11k files not deleted (sic!)“”
- Delete registry key (or rename it) HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\14.0
- Delete %AppData%\Roaming\Microsoft\VisualStudio\ and %AppData%\Local\Microsoft\VisualStudio\14.0\ComponentModelCache
Only after this steps I was able to reinstall VS2015 with success and no more pop-up Errors.
