Total Required Space

SebSpiers · Postby **SebSpiers** » Wed Jan 18, 2017 9:36 am

So, and I guess this could be a very silly question, but on the "componentstree" dialog there is a $TotalRequiredSpace$ label/value defined.

I've tried setting the variable within my script; eg:

Code: Select all

Set Variable TotalRequiredSpace to 3000000000

This doesn't seem to work, the installer shows this with a value of 0... where am I going wrong?

I've searched forums and googled with no luck!! I was expecting it to be a pre-defined variable, but it's not listed. :?:

Dear SebSpiers,

by default the TotalRequiredSpace Label gets populated via "Dialog Object Behavior". Doesn't exist any Pre-Defined variable at such purpose.

As reported by the IA Documentation;

Disk Space Calculations

If your products installation is reporting estimated disk space requirements as 0 or inaccurately, you are not making proper use of the Get Component State command in your script. InstallAware requires this command be used at least once in your installation to be able to accurately predict target disk space requirements. Please see the command reference for more information.

In case you want to display the value of a variable using a label dialog control;

- in your script, declare and intialialize your variable (Set Variable MY_VAR to xxxx) before to display the dialog.
- Load the dialog into the Editor.
- enter $MY_VAR" into the "Caption" property of the label.
- select "NONE" with the "Receives Information" field in "Dialog Object Behavior" (From Dialog Editor, double click the Label Control).
