I am running a fresh install of Windows 11 trying to set up a local SQL server for development.

I installed SQL server 2019 from ISO, however am unable to start the server. Same method of install and ISO works fine on my Windows 10 machine.

I have searched online and have seen similar issues posted.. however have not been able to find a solution or workaround.

Error from Event Viewer:

    @AaronBertrand I have tried this on CU11-13 and all give the same issue. The bottom stack is from the SQL Server LOG folder, only event view is showing an error. Also, not sure if this is related in anyway, but in the SQL LOG it is saying I'm running Windows 10 Pro rather than Windows 11 Pro... Developer Edition (64-bit) on Windows 10 Pro 10.0 <X64> (Build 22000: ) I am now getting the same failure but with ntdll.dll instead. Oct 11, 2021 at 20:08
  • @AaronBertrand The only logs in that folder are titled ERRORLOG. I am getting this error before the server even boots for the first time. Just removed all SQL related programs as well as Visual Studio and did a reinstall... got the same error at the end of install when it tried to start the server. Oct 11, 2021 at 21:11
  • You're seeing WER output which isn't very helpful for a multitude of reasons. ` Exception code: 0xc0000005` is an access violation, the location isn't helpful due to ASLR since you don't know the base. You'd need to use procdump or such as get an actual dump of the process and check the faulting stack. Normally the errorlog will have this information though it could be happening on a non-SQL server created thread, thus not conforming to the exception handlers that SQL-created threads install.

  • It doesnt work on upgrade, nor on fresh install of Windows 11. I have messaged SQL Server team on Twitter. I am not sure how it will go ahead. If I get anything in response, will post here. Oct 13, 2021 at 3:11

It looks that it just needs to be installed on second disk, weird, but I tried it and it just works.

Basically you have 2 options:

  • Install the instance on the second disk and leave the shared components on Disk C (it should be greyed out so it is not even option here)
  • Install SQL Server 2019 in a linux container (docker) under WSL2

I tried first option and it worked and my colleague tried second option using docker and WSL2 and it also works

  • Installing it on a Linux container solved my Issue. Thanks! Mar 7, 2022 at 15:25
