Hi again Apparently, the issue is on the VM side. I unpack the 9.0 VM into the 8.0 folder, and everything went fine. Looks like there is an issue on windows when getting the latest 8.0 VM. Looking the the dev mailing list, I can see a similar issue has been raised, when you have unzip program on your computer, that can corrupt the VM extraction archive Renaud Mar. 11, 2020, 13:38 by renaud.devillemeur@tuta.io:
Hi.
Are there any recent update with PharoLauncher ? It worked fine yesterday, but today I cannot launch default 8.0 image. It fail with a debug message: Instance of ZnBufferedWriteStream did not understand #name. I'm surprised to receive such message, and can't find out what has change to get suddenly such behaviour.
Pharo Launcher is the latest version: Pharo 1.9.2-2019.08.01 - This distribution was built August 01, 2019.
I'm using default Pharo 8.0 VM and Image, all refreshed to their latest version. However, the launcher is working well with default Pharo 9.0 VM and Image.
Here is an extract of the log (full log attached) Instance of ZnBufferedWriteStream did not understand #name 11 March 2020 10:51:09.200161 am
