Disk space information variables return empty value
Hi,
I need to show the disk space information in pre-install summary panel. As a pre-install Summary Panel, I am using Scrolling Message Panel with HTML format. To get the disk space information I have used the IA variables. $REQUIRED_DISK_SPACE_BYTES$ and $FREE_DISK_SPACE_BYTES$.
[HTML]
Disk Space Information (for Installation Target):
Required : $REQUIRED_DISK_SPACE_BYTES$
Available : $FREE_DISK_SPACE_BYTES$
[/HTML]
When I run the installer, I'm not getting any value in these variables. How can I resolve this issue? Is there any alternative to get the disk space information?
Thanks & Regards,
Achu

Hi, the Pre-Installation Summary Panel can automatically show this information.

Thanks for your reply!
But I cannot use the default pre-install summary panel. Because I need a different look and feel for the summary panel than the one which we get from the pre-install Summary panel given by IA. I think, i cannot customize the default pre-install summary panel to meet my requirement.
Is there any alternative to get the disk space information?
Why these variables return empty string? is it a usage problem?

The only reason I could see comes from the manual:
So you need to have this panel as the last one in the Pre-Install task.
The variable gains its value immediately before the installation of any files or folder listed in the Install task.

Yes. This is the last panel in pre-install phase.

Can you post your project (or a mockup project of what you're trying to achieve)?

Well, if your installer doesn't bundle anything, maybe that would be the reason?

In my sample project,i bundle a folder($IA_PROJECT_DIR$\install\winscp). I have used install speed folder action to install this folder (winscp) in to the user install directory. I think this is how we bundle files.

Yes, but when I ran your example I didn't have SCP so the final installer contained nothing.

I don't know for what reason, but the two variables seem not to be available at that moment: I've set an Output Debug Information right before your panel and the two variables are missing from the output...
