I made a program that connects to QuickBooks to automate a task. And it relies on QBFC13 so how can I make sure that QBFC13 is installed before installing my program. Or is there a way to install it first?
Not familiar with QBFC13 but why not use WiX and WiX Bootstrapper to build your installs and chain them together?
I just looked up this product and it looks like Intuit builds merge modules (MSM) for just your scenario. After installer their SDK I would find the specific merge module and then include that in your install.
