Software Deployment

What is the best way to update an module.ini file in an existing ica32pkg.msi file?

Here is what I did:
Right clicked on package and opened the package for editing in Wise Package Studio 4.5.
Went to .ini files section
Changed the drope down from all features to ICA client
Created a folder under where the module.ini files resides
Imported the new module.ini file in that folder

Went to the files section
Created the folder structure where the module.src file (corresponding file to .ini) resides
Added the updated file in the folder

Clicked on Compile and got the error:
Line 140, Column 1
Description: Could not find row with key value 'Current User'.

I am not sure how totroubleshoot this issue.

Is there any other way to update an .ini file in an existing .msi?

Thanks
