System requirements

Operating system

Supported operating systems: Windows 98, ME, 2000, XP, 2003, Vista, 7.
Run Visustin on the Mac the same way you run other Windows programs.

Hardware requirements

Visustin runs on any modern Windows PC hardware.

HardwareRecommendedTested minimumComment
RAM2 GB32 MB512 MB is OK, adding RAM helps up to 2 GB
ProcessorPentium 4 or betterPentium 120 MHzRuns faster with a fast processor
Monitor1280×1024 or more640×480The bigger the better
Disk free10 MB10 MB

The Recommended hardware is where Visustin runs very well. For a great view into your flow charts use a large monitor (1920×1080 or bigger).

Old hardware? If your PC is from the 2000s, it can run Visustin. Visustin even runs on the Tested minimum hardware, but it does that slowly and only produces small charts. RAM is the main limiting factor on old PCs. Extend RAM and increase the system's virtual memory to get power.

Required files

Visustin setup installs the following files. They are required to run Visustin. If you get errors, make sure you have run setup. Run Checklib (see below) to determine if a file is missing.

Installed file        Size  Date      Version       Required for

zlibwapi.dll        74,240  18/07/05  v1.2.3.0      Save/load PNG, save PDF

Later file versions are usually compatible. Exception: WinGraphviz.DLL must be v1.0.2.17, not newer.

In addition, the following files are required, but not installed by Visustin. They are installed by Windows and you already have them, unless someone deleted them. Use the version that already exists on your system. Newer versions should be compatible.

Not installed         Size  Date      Version required
ASYCFILT.DLL       147,728  02/06/98  v2.30.4261.1

CheckLib

If you run into errors, verify correct installation of the above files by running CheckLib. It verifies that the required run-time files have been correctly installed on your computer. You can find it in your Visustin directory. Double-click CheckLib.exe to run it. CheckLib locates the required files on your computer and checks to see whether the available version is the same as or higher than the required version. If any problems are found, it will suggest what to do next.

Export requirements

Export functionality requires the following applications installed on the same computer as Visustin. Later versions of these applications may not be compatible.

Visustin does not require any specific programming environment installed on your computer.

Digital signature

The following files are digitally signed by Aivosto Oy: visustin.exe, visustin.dll, visustin.cab, strtch.dll, st6unst.exe, setup.exe, setup1.exe, config.exe, checklib.exe. If one of these files has no valid signature or is signed by someone else, Aivosto Oy cannot guarantee its safety or correct operation. In this case, load a safe virus-free copy from www.aivosto.com.

Warning. Modified copies (not signed by Aivosto Oy) may not be used. Modifications may be infected with malware. Aivosto is not responsible for any damage or virus infection caused by such an illegal version.

Root directory write access

Visustin requires write access to some root directory (C:\, D:\, ..., Z:\). Visustin creates some small temporary files in there during the flowcharting process. This may cause problems if the current user account has no write access to the root. With no write access, Visustin may crash. By default, Visustin uses the root directory on the drive of the working directory. For example, if the working directory at startup is C:\VISUSTIN, Visustin will use C:\.

If the initial root directory is not suitable, Visustin will search for a suitable drive starting with C:\ and proceeding up to Z:\. A suitable drive is a hard disk, a RAM drive, a network drive or a removable drive (such as a flash memory drive) with at least 3 MB of free space. In addition, write access to the root directory is required. There is no option to use a directory other than the root. If there is a problem finding a suitable drive, Visustin will show a warning. If you get a warning, try one of these solutions:

A. Create a new drive letter as a network share
Temporary files will be created on the new drive letter. Follow these steps:
  1. Create a new directory (say, C:\VISUSTIN_TEMP).
  2. Right-click it and select Sharing. Select Share this folder and give it a share name (say, VISUSTIN_TEMP). Make sure you give yourself write access to it.
  3. Open the Tools menu in the Windows Explorer and select Map Network Drive. Select any free drive letter (such as V:) and map it to the newly created share VISUSTIN_TEMP. The next time you run Visustin it will locate and use V:\.
B. Run Visustin as Administrator
System Administrator has enough rights.
C. Windows Vista: Disable UAC
In Windows Vista, UAC (User Account Control) may prevent you from writing to C:\. You can turn UAC off via Control Panel, User Accounts and Family Safety, User Accounts, Turn User Account Control on or off. In addition, you will also need Write permission to C:\.
Windows 7 may have the same issue, but the default settings should work fine.
D. Add a USB drive or flash memory card
As a last resort, add a USB stick or flash memory card to the system. Such a drive will usually give you root access. Note that this may slow down the performance compared to a regular hard drive.

Optimization. If the temporary files are being created on a wrong drive (a slow drive, for example), change Visustin to start in another working directory. Say you installed Visustin on a slow drive in D:\VISUSTIN. Change the initial working directory to your fast drive E:\. You don't necessarily have to change the installation path of Visustin, just the working directory.

Limitations

Binary source code files cannot be loaded. Copy & Paste your source code to Visustin to overcome this.

National characters are supported. Exception: Arabic characters are supported in Editor and Visio export, but not in the main window. Metafile and .ps file creation may fail for characters not in the current ANSI codepage. See Character set options for national character support details.

Limitations on Windows Vista

Visustin runs fine on the default configuration of Windows 7. If you have other settings, try the above list for a solution.

Windows 95 and NT not supported

Windows 95 and NT are no longer supported. Support was available for Windows 95 up to Visustin v4 and for Windows NT4 (SP3 or later) up to Visustin v5. Visustin is no longer being tested on these systems. It may not run at all. Known limitations are listed below.
