How to Pre fill wise installer Dialog

Question

I am trying to support this legacy application where we use wise installer to create our application installer. I can see that script will take parameters.

What I want is that when user run installer, the install dialog should have values pre-filled. For this I did some research and found that I can put those parameters in a file and then call installer with a tag and parameters file name.

Here is syntax that I tired

MyAppSetup.exe /M="C:\USERS\User1\DOCUMENTS\MyAppSetup.txt"

where MyAppSetup.txt has parameter names and it values. MyAppSetup.txt contents is as below

COMPANY="ABC"  
SERIALNUMBER="123" 
...   
...

Now installer runs correctly, but values are not prefilled.

But if I run the installer in silent mode, it dose uses the parameters correctly.

Here is syntax to run the same script in silent mode.

MyAppSetup.exe /S /M="C:\USERS\User1\DOCUMENTS\MyAppSetup.txt"

I would really appreciate if someone can guide me on how to call installer visually and have values prefilled.

Here are some useful links that I found

What are the command line parameters available for WiseScript?

Use a .ini file, then the installer will read those values and populate the dialog quite nicely. Here's an example of a C:\MyApp\MyAppSettings.ini:

[settings]
COMPANY=ABC
SERIALNUMBER=123

...and a .wse that will populate a dialog:

item: Set Variable
  Variable=MAINDIR
  Value=C:\MyApp
end
item: Set Variable
  Variable=COMPANY
end
item: Set Variable
  Variable=SERIAL
end
item: Read INI Value
  Variable=COMPANY
  Pathname=%MAINDIR%\MyAppSettings.ini
  Section=settings
  Item=COMPANY
end
item: Read INI Value
  Variable=SERIAL
  Pathname=%MAINDIR%\MyAppSettings.ini
  Section=settings
  Item=SERIALNUMBER
end
item: Custom Dialog Set
  Name=My App Settings
  item: Dialog
    Title=My App Settings
