To ensure integrity, Microsoft provides SHA-256 checksums on the download page (accessible after initiating download media). Example command (PowerShell):
Get-FileHash .\SQLServer2022-x64-ENU-Dev.iso -Algorithm SHA256
Compare the output hash with the value listed on Microsoft’s download site.
These are official Microsoft download links (you may need to paste into your browser):
🔁 Microsoft changes link redirections occasionally. If these fail, use the bootstrapper's "Download Media" method – it always works.
📌 Important: The button downloads a small bootstrapper (setup.exe ~6 MB) by default. We need the full offline ISO or CAB.
For enterprise scenarios, the Volume Licensing Service Center provides the .ISO images directly. However, this is generally reserved for Standard and Enterprise editions under paid agreements.
Once you have the offline media:
Q: Is the Developer Edition offline installer really free? A: Yes. It is completely free, no time bomb, no expiration. The only restriction is you cannot host production data.
Q: Can I use this ISO on a server with no internet (air-gapped)? A: Yes. That is the primary use case. However, you may need to manually install .NET Framework 4.8 or Cumulative Updates (CU) if they are not included in the base ISO.
Q: How is this different from the "Express" edition offline installer? A: Express is also free but has hardware limits (1GB RAM, 10GB database size). Developer has no limits but cannot be used in production.
Q: Can I convert the Evaluation ISO to Developer?
A: Yes. Download the Evaluation ISO (180-day trial) and then run the Edition Upgrade wizard within the setup. You can convert it to Developer without re-installing. However, it is cleaner to download the Developer ISO directly.
Q: I downloaded the ISO, but installation still asks for internet – why? A: You likely selected "Install R Services (In-Database)" or "Machine Learning Services." Those require extra Python/R packages that are not on the ISO. Deselect those features for a true offline install.
