Cannot get %AppFolder% in .ini value field

[Kolo]

I am creating an .ini file during the post-install and one of the settings is for a Local Directory. This of course is based on where the installer chose to install the app.
I've tried ...
INIFile.SetValue("%AppFolder%\\SoftwareFTPConfig.i ni", "ProgramDownload", "LocalDir", "%AppFolder%\\Program Updates")

and...
INIFile.SetValue("%AppFolder%\\SoftwareFTPConfig.i ni", "ProgramDownload", "LocalDir", _AppFolder.."\Program Updates")

and
cString = <concatenated string>

INIFile.SetValue("%AppFolder%\\SoftwareFTPConfig.i ni", "ProgramDownload", "LocalDir", cString)

None of these work - I get a literal representation of the value (e.g. "%AppFolder\...") every time.

Can anyone help?

Thank you , Kathy

Hello,

Of course you have to expand the session variable before you can use it. You are using "%AppFolder%" as a string, not as a session variable. To get the contents, use

folder = SessionVar.Expand("%AppFolder%");
INIFile.SetValue(folder .. "\\SoftwareFTPConfig.ini", ...

or

INIFile.SetValue(SessionVar.Expand("%AppFolder%\\SoftwareFTPConfig.ini"), ...

This is well explained in the documentation, examples, and here.

Thank you for your reply.
However, I still have an issue.
The issue is not with the folder reference it is with the value of the .ini property.

When I try
cVal = SessionVar.Expand("%AppFolder%");
INIFile.SetValue("%AppFolder%\\ProductFTPConfig.in i", "ProductDownload", "LocalDir", cVar.."\Table Updates");

on 'Post Install' I get this error at install time...
On Post install, line 10: attempt to concatenate global 'cVar' (a nil value)

Any suggestions?

Thanks again, Kathy

cVal = SessionVar.Expand("%AppFolder%");
INIFile.SetValue("%AppFolder%\\ProductFTPConfig.in i", "ProductDownload", "LocalDir", cVar.."\Table Updates");

You've used two different variable names for the folder string (highlighted in red).
