BioStar 2 Revision Notes

- Installation files for 32-bit operating systems are not provided from BioStar 2.9.2.

- Do not install BioStar 2 on a PC where BioStar 1 is installed. This may cause performance problems.

- If BioStar 2.3.0 is installed on top of a BioStar 2.2.1 or 2.2.2 installation, all information stored in the SQLite database is migrated to a new MariaDB database.

- Upgrading directly from the existing version to the latest version is possible from BioStar 2.6.0 or higher. If the installed version is lower than 2.6.0, installing all versions in a correct sequence until reaching version v2.6.0 is essential.

- If you are using Windows 8.1, install the KB2919355 update by referring to the following web page.

- If you are using MS SQL 2012 Express, install the Service Pack 3 by referring to the following web page.

- If you are using MS SQL 2014 Express, install the Service Pack 2 by referring to the following web page.

- Starting from BioStar 2.9.9, MS SQL Server 2022 is supported, and you can connect using either the Microsoft OLE DB Driver for SQL Server or Native Client.

• If the OLE DB driver is installed, BioStar 2 will use OLE DB as the default connection method. If only the Native Client is installed, the system will connect using Native Client.
  

• Since Native Client is no longer included with SQL Server 2022 and has limitations in terms of compatibility and features, it is recommended to use the OLE DB driver for connecting to newer versions of SQL Server.
  

- If MS SQL Server and BioStar 2 are installed on different PCs, the PC running BioStar 2 must have either the Microsoft OLE DB Driver for SQL Server or Native Client installed.

• When using the TA menu, the Microsoft ODBC Driver 17 for SQL Server is also required. Please verify your environment and install it accordingly.
  

- If you are using MS SQL Server, set the Collation option of the server and each table to CI (Case-insensitive).

- When backing up a database from an older version of BioStar 2, disable all services and procedures. Furthermore, if you do not back up and restore the AC database and the TA database together, you will not be able to use the TA database.

- If you want to back up the database of BioStar 2, be sure to also back up the enckey in the \Program Files\BioStar 2 (x64)\util folder and the system.conf and setting.conf file in the \Program Files\BioStar 2(x64) folder. Otherwise, the database will be unavailable.

- The default values for the ports used by BioStar 2 are as follows. If another program occupies the same port, BioStar 2 may not work properly.
