I had already had an impossibility to install corona on a machine, but as I had then changed computer, I had zapped the problem; now I would need to "reanimate" the old computer, and, with the installation of the 8, I find the problem intact: the installation window tells me that everything installs normally, I click "finish", but corona does not appear in the r20. ... is there a tutorial, instructions, to uninstall absolutely all components of corona, before reinstalling? thank you for your help!
