Hello! I attempted to update to the newest version of Scrivener today. Download completed, but when I installed, I got an error and the installation shuts down. I’m attaching a picture of the error because it’s not one that I’m familiar with.
If you download and run the installer from here: https://www.literatureandlatte.com/scrivener/download that should apply the update and give you access again.
I had the same problem and it appears these instructions resolved my issue.
In case it helps developers or users, I have my Scrivener 3 installed on a separate drive from my Windows drive. The Updater does not let me show the installer where to install, so it exits with this failure.
