Vive setup crashes when it says preparing in Vive and Vive Pro Posted June 10 I just had this issue where when I attempt to install Viveport, it gets to the Preparing stage for 1-3 seconds before the whole client crashes. But I found a fix that worked for me and hopefully it can work for you too. Step 1. Go to your Temp folder via C Drive > User > AppData > Local > Temp Step 2. Find everything that has to deal with HTC or Vive and delete it from that folder. It's going to be a long list of files with a bunch of numbers/ect so scroll down until you find the files. Step 3. After deleting every HTC and Vive file within that folder, then attempt to reinstall Viveport. Hope this helps anyone who has this issue.
