I have just installed Win 7 over win10 but I cannot reinstall s3d, it tells me I have already got the quota installed.
These I found in WIN old and Winooo they have been uninstalled but I still cannot install s3d.
Some help would be appreciated, thanks

Just send a message to their licensing team and I'm sure they will help: https://www.simplify3d.com/contact-us/
