Well,
- Your error message had already indicated what went wrong:
- The installer file you downloaded might be corrupt or had a missing DLL file. As a result your upgrade failed. That is the essence of that message.
- Unfortunately, the failed upgrade installation made a mess of the original system disk.
- It left behind some files in your system disk's root that would block any further attempted upgrade as happened to you.
- It also left behind a useless "Installer icon" in your CBM screen
- I advised you to remove the left over file bits and redownload the macOS Installer file .
- I advised you to check the integrity of the file using md5 checksum or sha-1 before trying to perform another upgrade install with it or
- better still a clean install using a newly created USB installer on the hard disk to make sure the disk has no further interfering files from previous install to cause another boot issue.
- You had your own reasons not to pursue that.
- I don't know of any other way to perform a 'post mortem analysis' of the prior upgrade crash or a need for that when the answer is already very obvious and supported by your current post that says
- I tried several versions of the installer, and I am sure it was not the download: I had also tried with the download I used to create an USB stick with on a mac later. And that boots without panic.
- When the installation fails, the kernel panic happens right in the beginning of the installation process. I do not think any files have been moved at that point.
- The original system disk is not a mess - it is fine - I can still boot Sierra from it without any problems - the systems seems completely unchanged - despite the Installation folder in the root directory. I can remove that - and the Installer Icon disappears.
- I did followed all your advice, and it did not help - no problem there - I am thankful for your comments - I know you are trying to help!
- You had also mentioned that I might have something installed that is not compatible with High Sierra, causing the panic - and instead of doing a clean install, I wanted to keep my configuration, installation and everything instead of doing everything all over again. I guess that's a reason one can understand.
I fear I'll have to do another clean install - I was quite glad that my system just worked - and I was able to install the last updates without problems...
Thanks for trying to help...
