- Microsoft Visual C++ Redistributable libraries are required for some drivers. Download and install them from Microsoft if you get errors saying "vcruntime140.dll missing".
- Linux:
- Installation of deb package:
- per double-click in the application center
- or per command line:
sudo apt install ~/Downloads/debfile

Preview v13 Windows version
Future releases will be based on an entirely migrated codebase, the same as already used for the Linux version. The migration started in Feb 2025 and is already well advanced. There is no timeline for a stable release yet. However, a preview can be downloaded here (updated on 2026-02-10). Unzip it in your existing HeidiSQL directory, and you can use both version in parallel:
- C:\Program Files\HeidiSQL\
- or C:\Users\[username]\AppData\Local\Programs\HeidiSQL\
Latest changes and nightly builds
Latest automatically compiled main executable and installers for HeidiSQL. Just download and overwrite your existing C:\Program Files\HeidiSQL\heidisql.exe. Be aware that these builds are not official releases and therefore probably have more bugs, possibly serious ones.
