I have a big problem when i want to launch a msi file with a custom action.
I have create a property MSIEXEC with the value msiexec, and i use it to create a custom action who launch an executable.
My custom action target is :
/i run1.msi /qb
and i have copy run1.msi and its subdirectories in the directory of my main msi.
thank you for your help !
