Installation (Windows) 0212

If a previous version of Balsac is installed in your PC you have to remove all system files of the previous version with the uninstall feature of your windows system before you can install the new version. Note that any old Balsac input/output files should be kept for later use

INSTALLING: Balsac (Version 4) requires that you have Administrator status on your PC and consists of four steps.

1.      Unpack all files by running (the downloaded) file Balsac4_x_Install.exe. This will ask you for the name of an installation directory, e.g. c:\temp (or any other temporary directory, which must be different from the permanent directory where you wish Balsac to be installed). This directory (called $temp below) will contain all system installation files and a file Readme.1st which describes latest changes and gives further advice concerning the installation. Note that the installation directory cannot be used as the final Balsac directory, see step 2.

2.      Install all Balsac files by running Setup.exe inside the installation directory (see step 1). This will ask you for the name of the final Balsac directory where "c:\Program Files\Balsac4" is used as a default. This directory will be called $Balsac in the following.

3.      Install the Compaq fortran runtime libraries by running VFRUN660I.exe in directory $Balsac.

4.      Clean up by removing all installation files from directory $temp. You may leave the original download file Balsac4_x_Install.exe for backup purposes.

You can inspect the Balsac users manuals balsac4.chm and balsac4.hlp in directory $Balsac\.

Note that

·        Starting with version 4.1 of Balsac the new html based help option (default for MS Windows 7 and later) is available by default but the traditional Windows help can still be used as an option. Microsoft, in its wisdom, has discontinued providing the traditional Windows help engine (WinHlp32.exe) with MS Windows 7 and later by default. The absence of inHlp32.exe in your PC will make the old Balsac help option unavailable. However, WinHlp32.exe can be downloaded from Microsoft at and installed in your Windows PC free of charge. This will enable the traditional Balsac help option if needed.

·        Microsoft does not include the Visual Basic 6 runtime environment (required by Balsac) in its Windows 8, 8.1 versions by default. However, the VB6 runtime environment can be downloaded from Microsoft ( and installed in your Windows PC free of charge. This will enable Balsac to run also under Windows 8, 8.1.

·        Balsac will work successfully in your national (other than US) Windows environment ONLY if real numbers follow the US convention of using "." (period character) as the decimal separator symbol and "," (comma character) as the digit grouping symbol. Number symbols, like the decimal separator and digit grouping symbol, can be reset in the Regional Settings part of your Microsoft Windows Control Panel.


RUNNING: Balsac can be run interactively from scratch or using input files to be combined with the corresponding executable where correct directories must be provided. A typical Balsac run can be started

·        from the Windows file explorer:
Double-click at the corresponding input file of the listing, “*.lat”, “*.plt”, “*.xyz”, “Balsac.svl”, or “Balsac.svc” or double-click at the Balsac executable to run from scratch.

·        from the Command Prompt Window (DOS box):
Open the command crompt Window (DOS box) inside MS Windows. Move to the directory where input files, *.lat, *.plt, *.xyz, reside and type "\$Balsac\Balsac4 infile" (to start with an input file) or "\$Balsac\Balsac4" (to start from scratch) followed by the Enter key.

·        from the Windows command line:
Choose "Start | Run..." from the taskbar; then type "\$Balsac\Balsac4 \$dir\infile" where $dir denotes the directory path where the input file resides and press the Enter key or type "\$Balsac\Balsac4" and press the Enter key to start from scratch.

Typical Balsac input example files are contained in directory $Balsac\Examples.
