Installation notes

Windows:
- HeidiSQL runs fine on Windows 11 x64 (and on Windows 10 x64 with minor issues).
- Microsoft Visual C++ Redistributable libraries are required for some drivers. Download and install them from Microsoft if you get errors saying "vcruntime140.dll missing".
- A preview of v13 can be downloaded here (updated on 2026-04-21 17:00). Unzip it in your existing HeidiSQL directory, and you can use both version in parallel.
Linux:
- For the .deb and QT releases, Ubuntu 24.04 needs libqt6pas (not in the repos yet):
  - curl -L -o /tmp/libqt6pas6_6.2.10-1_amd64.deb https://github.com/davidbannon/libqt6pas/releases/download/v6.2.10/libqt6pas6_6.2.10-1_amd64.deb
  - sudo apt install /tmp/libqt6pas6_6.2.10-1_amd64.deb
- Install package:
  - DEB: sudo apt install ~/Downloads/debfile
  - RPM: sudo yum install Downloads/heidisql...rpm
- Settings are stored in a .json file. You may migrate your settings from a Windows registry:
  1. click File > "Export settings" (to .txt file) in the Windows version
  2. click File > "Import settings" in the Linux version

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.

fix: MSSQL foreign key lookup to include table schema

Use the fully qualified database/schema/table name when resolving
OBJECT_ID() for MSSQL foreign key metadata. This prevents SQL Server from
implicitly resolving tables under dbo when the table belongs to another
schema.

Also include the referenced table schema in the foreign key metadata so
references to non-dbo tables are preserved correctly.
