Hi Robert,
Did you by any chance install on a drive other than C:\?
Unfortunately we have a dependency on something called 8dot3names (https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/fsutil-8dot3name), which is not enabeled on drives other than C:\ by default. So to avoid any issues related to that, you'd either have to enable 8dor3names on the drive you want to install on or refrain from using paths that contain file or folder names longer than 8 characters, such as "D:\Program Files". Just use "D:\" as the target path instead or if you must use a specific folder, keep the name short, maybe "D:\OCI" would do.
Also, the install logs that you can find in ..\SANscreen\bin\log and should be copied out prior to the rollback, is usually more helpful than the screenshot.
