If I accept the defaults and install with the german language pack the installation succeeds, so no harm there, just wanted to report this, so the next person can get a better error message.
De-Install my old installation of the Rhino 7 WIP, as i assumed the installer might get confused by it. -> Still did not work
finally: Out of a hunch, Disabled the option for the english language pack in the installer -> Rhino 7 installed successfully and works as expected, though I typically don’t use the default german language pack normally.
The takeaway for me is, that the error message and also the solutions found here on the forum did not help to find what seems to have actually caused the error on installation. Maybe there is some info in the log, that can help supply a more fitting error message.
Yes, you are totally right, the first few times I tried to install, I entered the license key directly in the installer, but as you can’t copy paste into the installer fields, I got lazy after a few failed attempts .
Help me please. I downloaded the Rhino7 trial yesterday and I can’t install it, this same error appears and I can’t fix it. I followed all the guidelines I read here, but nothing resolved.
In order to work around this, you need to just click the “Install Now” button on the installer without clicking the Gear button. Once Rhino is installed, you can enter your license key. If that doesn’t work, please DM me the install log file that is shown in the installation failure dialog box.
