FDS 4 & FDS 5 on the same Computer

[Ronny]

Guys,

does anyone have any problems running FDS4 on a computer after
installing FDS5 on it?

We run FDS over a server from a separate computer designated for FDS,
however after we installed FDS5 on it we cannot run old FDS4 files
anymore. We have FDS4 & 5 installed in different Subfolders.

Getting the following message:

'FDS is not recognized as a internal or external command, operable
program or batch file'.



Any ideas how to fix this?


Regards

Ronny

When you type a command (for example the name of an executable file)
at a Windows command prompt, the command prompt will essentially do
two things:

1. Look in the directory you are currently in, and see if that file
exists in that directory

2. Open the environment variable PATH and look if the file exists in
any of the directories listed in that variable

That means that if you browse to the directory in which you have
installed FDS4, typing the name of the fds4 exectubale (by default
fds4.exe but you can omit .exe) will execute it.

If you are not in the fds4 directory, but in another directory,
perhaps where your model files are located, the path to the fds4
directory must be in the PATH variable. If it is not, the command
prompt can obviously not find fds4.exe and will output the error
message you got. This is pretty logical behaviour, because the only
other solution would be for the command prompt to search your entire
harddrive(s) for that particular executable which obviously would not
be such a good idea.

Solution: Goto Control Panel->System. Goto "Advanced" tab, click
"Environment variables". In the lower box (System variables), find
PATH, press "Edit" and at the end of the text string (do not change
the existing string) add a semicolon and then the path to the
directory in which fds4.exe is located.

If you have a command prompt open, you have to close it. When you open
a new one, you will be able to start any exe file in the fds4
directory regardless of the actual directory you are currntly in in
the command prompt.

Thx Tom, I'll give it a go.
