Visustin – System requirements

Help » Info » System requirements

Operating system

Supported operating systems: Windows 2000, XP, 2003, Vista, Windows 7, Windows 8, Windows 10.

Visustin is a Windows program that processes code written for Windows, Mac, Unix, DOS, mainframes and other environments. Run Visustin on the Mac the same way you run other Windows programs.

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

Hardware requirements

Visustin is at its best on a modern, well-equipped PC, but it does run on outdated hardware as well.

• Monitor: The bigger the better. At least 1280×1024 px recommended, preferably 1920×1080 or more.
• Printer: A4 or Letter size printer is fine. Big size printers and plotters are preferred.
• Processor: No specific requirement.
• RAM: 2 GB is fine. Over 2 GB makes no difference.
• Disk space: 10 MB.

You won't need a new PC for Visustin. If your PC is from the 2000s, it can run Visustin. Tested minimum hardware is Pentium 120 MHz with 32 MB RAM and 640x480 monitor. With old PCs RAM is the key limiting factor. 512 MB RAM is good enough.

Required files

Visustin setup installs the following files. They are required to run Visustin.

WinGraphviz.dll must be v1.0.2.17, not newer. Later versions of other files are usually compatible.

* You may edit this file with Visio.

If you get errors, make sure you have run setup. You can use CheckLib to verify that. CheckLib checks if the required run-time files have been correctly installed on your computer. CheckLib is in your Visustin directory. Double-click CheckLib.exe to run it. If CheckLib finds any problems, try running Visustin setup to install the missing files.

Export requirements

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

• Visio export requires Microsoft Visio 2003/2007/2010/2013/2016.
• Word export requires Microsoft Word 2007/2010/2013/2016.

Digital signature

The following files are digitally signed by Aivosto Oy: visustin.exe, visustin.dll, visustin.cab, 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 7/8 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.
