System requirements

Operating system requirements

Supported operating systems: Windows 98, ME, NT4 (SP3 or later), 2000, XP, 2003, Vista.
Recommended operating systems: Windows 2000, XP, Vista.

Hardware requirements

Visustin runs on almost any modern PC hardware with 10 MB of free hard disk space.

Makes small charts, slow.

Extending RAM up to 1024 MB helps with large charts. You can also increase the system's virtual memory size.

Small charts are possible on even the less powerful systems. Large charts (around 100 kB or 3000 lines of source code) require more modern systems. To test your system's performance, open a large source file in Visustin and press Draw.

Required files

These run-time files are required for Visustin to function. Run the Visustin demo setup to ensure they are installed.

Visus5.vst                                          Required for Visio export.

Later file versions are usually compatible. The exception is WinGraphviz.DLL, for which the exact version 1.0.2.17 is required. Files marked Installed by Windows are Windows built-in libraries. They are not installed by Visustin.

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.

CheckLib

If you run into errors, you can verify correct installation of the above files by running CheckLib.exe in your Visustin directory. CheckLib is a little utility that 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.

Digital signature

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

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:

1. Create a new drive as a network share
Visustin will create the temporary files on the new drive.
2. Run Visustin as Administrator
System Administrator has enough rights.
3. 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:\.
4. 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 need 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.
