This could be the result of one of the following:
- Using a license key intended for a different version, e.g. Pano2VR V3.0 key with Pano2VR V4.0
- Using a license key for a different Garden Gnome Software product, e.g. Pano2VR key to try and activate Object2VR.
- A space is added when copy and pasting; look at the start or end of the key and remove any added spaces.
- In some cases it’s possible that the incorrect characters were used; I (upper case i), l (lower case L) and 1 (number one) look very similar, the same goes for 0 (number zero) and O (upper case o).
