## VITESS Installation under Windows

This version comes to you as a self-extracting .exe file.
When your browser asks for a file name to store the self-extracting file,
it might suggest
`vitess_download` or `vitess_download.html`
which you should change to an executable name like
`vitess_download.exe`

After downloading this file to your computer, please execute this
file e.g. by double-clicking the file name within the explorer.
By July 17 2001 this file may be checked by cksum (CRC32)
786462490 5383522 vitess.exe
and md5sum (MD5 message digest)
76d9819033a714710c29c545bd5a2612 vitess.exe .

This brings the setup program to life, which will ask you few
questions, like that where to install VITESS on you disk.
After successful installation you might delete the file
`vitess_download.exe` .

If you installed the full version with tcl version 8.8.1 files included,
double-clicking the VITESS item on your desktop should start the application.

If you installed the minimal version, the desktop symbol might not link to your installed
tcl software. Let us assume you installed tcl at `C:\Programs\tcl` and VITESS to
`c:\Programs\vitess.` Please change the program shortcut (link) on your desktop:

VITESS start command
`C:\Programs\tcl\bin\wish81.exe -f Vitess`
working directory
`C:\Programs\vitess`

To uninstall VITESS you might use the uninstall item in the command (sub-)
menu (like START/VITESS/uninstall) or the windows 9x uninstall procedure for software
`START/settings/system/software` or German
`START/Einstellungen../Systemsteuerung/Software`.

#### Pipe Command Execution under Windows 9x

If you save a pipe command and execute it as a batch file in a MS-DOS shell window,
you might observe problems with temporary file sizes. Pipes in a MS-DOS shell are
executed strictly serial, with intermediate files storing command output.
These intermediate files may be too big.

With Tcl/Tk piped commands are executed (quasi-)parallel, with small intermediate
buffers in memory.

Solution:
1) start pipes from the VITESS GUI
2) Save the GUI setting with "save tcl" to a file e.g. `C:\c.tcl`
Start a separate wish (`C:\Programs\tcl\bin\wish81.exe`)
and source `C:\c.tcl` there.
