Users reported that when launching or working in Revit or Advance Steel in Windows 11, a Command prompt window referencing SQLDUMPER.EXE appears and disappears every 1 or 2 seconds.
Alternatively, Advance Steel window might show the spinning wheel looping, while the Command prompt window might appear and disappear too quickly to see its name.
Windows 11 Operating System.
SSD/NVMe Drives that have a sector size bigger than 4KB.
SQL Server is unable to start due to the unsupported file system. SQL Server currently supports sector storage sizes of 512 bytes and 4 KB.
Note: An update to Windows 11 might trigger this issue for SSD/NVMe drive systems with sector sizes bigger than 4KB. The issue was not present on previous versions of Windows, as the built-in drivers capped the sector size value.
Microsoft SQL Server 2014 LocalDB (2019 for versions 2024 and newer) is not correctly installed.
A more recent version than Microsoft SQL Server 2014 is installed.
Restricted permissions of Advance Steel or RVT folder in ProgramData\Autodesk.
See the following support page for information on how to Update your software.
To check if the sector size is greater than 4 KB, go through the following steps:
Start the Command prompt as Administrator and run the following command:
fsutil fsinfo sectorinfo C:
Look for the values of PhysicalBytesPerSectorForAtomicity and PhysicalBytesPerSectorForPerformance (shown in bytes). If any of these values are bigger than 4096 (like in the attached picture), proceed with the next step
Follow the steps from the Microsoft Article describing errors related to system disk sector size - Troubleshoot errors related to system disk sector size greater than 4 KB
Alternatively,
Add a registry key that will force the sector size to be emulated as 4 KB (similar to Windows 10):
To do so, download and run SetSectorSize.reg (attached in this article). This will automatically add the value * 4095 to the registry.
Note: Reboot the system after changing the Windows registry to see SectorSize modifications.
Find Advance Steel #### or RVT #### folder in C:\ProgramData\Autodesk
If the ProgramData folder is not found, see the following article for information on How to turn on hidden files and folders on Windows.
Right-click the folder, choose Properties, and choose the Security tab
Check if the permissions for users and administrators are set for Full control to Allow
Click Edit to change permissions.
Submit the changes through the Apply button.
Check SQL using the following steps: Investigating SQL Server LocalDB installation when working with Advance Steel / Revit.
If the previous steps didn't clear the behavior, try logging into a different Windows User and see if the same behavior occurs. If it does not:
Reset Revit to defaults:
Go through the steps in the following article to reset Revit to defaults: How to reset Revit to the installation defaults.
Deleted, then recreate the sqllocaldb instance (as described in Investigating SQL Server LocalDB installation when working with Advance Steel / Revit).
If resetting isn't working, go through the steps in the following Microsoft Support page to restore the Windows User Profile.
If the issue was introduced when upgrading Windows, roll back to Windows 10 whenever possible. See Recovery options in Windows.
