Good morning!  Yes, all other CS products work on my computer. However, all other CS products were purchased/installed via the marketplace in the sim itself. The 717 was the only product I purchased from Captainsim's website.  That said, I have an update: our IT switched me over to Admin and at least one of the installers I've had issues with is now working (so I was able to install the FSS E170/175 series).  I'm about to retry the 717+liveries momentarily.
