ORBX
I vented my frustration on their forums and was banned. Far from automating their purchase and support process, they've just increased the need for manual intervention ten fold - as their forum indicates. So with that I'm done with them.
A quick browse of your Orbx and P3D folder will show you otherwise. They didn't like my criticism and banned me for it. Absolutely the worst experience I have ever had.
ORBX - Not in Programs and Features, not in the folders they force into your AppData folder, not anywhere.
I just wasn't falling in line enough for them I guess. A quick view of your registry will leave you in shock at what they leave behind. Rumor has it, this is causing blurries again in the sim. Several other folders and files were though. Let's see how that works out for them.
