2 questions regarding using NSIS
I have just started to use NSIS for installation. I have 2 questions:

1) How do I check if there is any window folder still open before I install my program? I saw some examples that I need to provide the application/program name for comparison. What I need is just to close all opened window folders for users.

2) When using package wizard in VB6, there is a dependency file generated. I like to know if there is an easy method to check the dependency by NSIS. I hope to use NSIS to replace the wizard from VB6. If this is too difficult, then may be just stay with VB's packaging wizard.

Thank you!
