To Install a package you have two options

1) Run dfpm from the workspace folder

Lets say for example your DataFlex workspace is in the following folder (the folder where your workspaces SWS file is)

D:\VFExamples\DataFlex 19.0 Examples\Order Entry

you can then open an Administrative command prompt and navigate to the workspace folder and use the install command as follows

Step 1

then call the install command to install a package

if you do not want to navigate to the workspace folder you can also specify the workspace using the -w option with the install command instead
