I purchased a new blower door system from retrotec and it came with the fantestic software. Unfortunately it only runs with Windows, I dont know why the hell anyone only makes a software compatible with only Mac or Windows, but i guess they only care to satisfy half of their audience.
Anyways, the software sells for $295 from Retrotec, I'll sell you mine for $150. If you're interested please email me: email@example.com
Please dont respond here, i dont check this often at all, I will delete this post once its gone.
