_techie_ Posted September 27, 2019 Posted September 27, 2019 Hi Running Windows 10 LTSC 2019 with VS 2017 Community Edition. All students have Microsoft accounts using Office 365. When signing into Visual Studio, it shows the trial license file has expired. When trying to download an updated license file we get the error: "we could not download a license. Please check your network connection or proxy settings". I have tried a number of users with the same error. We are using Smoothwall with HTTPS interception, but I cannot see for the life of me what is blocking this, either from a web filter side of things, or firewall related. I have tried numerous users with different permissions logging in, and also different IP locations around the site with the same problem (to avoid HTTPS interception). I have also tried the following after several forum posts/searches: 1) updating Visual Studio using the inbuilt Visual Studio Installer 2) Repairing Visual Studio " " " " " " 3) Setting IE as the default browser 4) Adding a line to the devenv.exe.config file to include a proxy setting (from Microsofts own site) but this just breaks VS, and it wont launch or gives errors 5) Given up! Any ideas/solutions to this one? Thanks
Benner900 Posted September 27, 2019 Posted September 27, 2019 Hi techie, We are having exactly the same issue today, It was working fine yesterday. We have a similar setup using VS2017 Community with Students O365 accounts, Also tried our Backup Broadband connection with no firewall or Proxy Server and get the same results. I have now put it down to a Microsoft issue and was on here looking to see if anyone had a similar problem to verify my suspicions. Also tried Hotmail accounts etc. rather than enterprise O365 accounts and no difference. From looking at Wireshark traces its connecting to our proxy fine and traffic is being sent back and forth when the request licence file is pressed but the error is still given. We have Sophos UTM's so its not a Smoothwall issue either. Was going to see how it looks on Monday now as I have ruled out most things here. Ben
sonofsanta Posted September 27, 2019 Posted September 27, 2019 (edited) Spent all day hammering at this one too! Up to and including "sod it, I'll download and install 2019", which hasn't fixed the problem but has at least started a new 30 day trial. I've fixed it in the past by running cd "C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\Common7\IDE" devenv /resetuserdata but that's doing sod all today. Gave up around lunch figuring it might be Microsoft's end and I'll try again next week. Seeing you lot with the same issue makes me think I made the right call there! I was going through Fiddler logs--it makes three calls every time you click that link, and the last one (when you went to the URL in a web browser) was returning nowt but null, so I suspect it is them.

_techie_ Posted September 27, 2019 Author Posted September 27, 2019 Glad its not just me then... I'll have a bash at 2019 whilst I'm waiting.
free780 Posted September 27, 2019 Posted September 27, 2019 Visual Studio 2017 isn't supported on LTSC. Maybe MS are making good on that requirement. Can you try a SAC version?
_techie_ Posted September 27, 2019 Author Posted September 27, 2019 SAC? I assume you mean education?
_techie_ Posted September 27, 2019 Author Posted September 27, 2019 Seems your right.... https://docs.microsoft.com/en-us/visualstudio/productinfo/vs2017-system-requirements-vs Great.. thanks for that Microsoft! My fault for not checking the system requirements. Why doesn't it fail the install fgs!
free780 Posted September 29, 2019 Posted September 29, 2019 From MS' point of view LTSC is only meant for boiler control PCs etc. If your developing for current versions of Windows you'd be using SAC.
sonofsanta Posted September 30, 2019 Posted September 30, 2019 Visual Studio 2017 isn't supported on LTSC. Maybe MS are making good on that requirement. Can you try a SAC version? TBF, I think this issue is wider than that requirement--we're just on 1803, not any LTSC version.
Benner900 Posted September 30, 2019 Posted September 30, 2019 I've just tested VS2017 here and the issue is resolved. Must have been an issue at Microsofts end. Ben
_techie_ Posted October 8, 2019 Author Posted October 8, 2019 Yep, seems to have been resolved. After re-imaging my VS suite to Win10 Education.... teacher PC remains on LTSC and is now working.. FGS!
free780 Posted October 8, 2019 Posted October 8, 2019 Welcome to the SAC club. May the odds be ever in your favour of chasing down that last 1607/1709 etc.
