--- Comment #3 from Jacek Caban jacek@codeweavers.com --- TestBot uses MSI files, which requires those MSI files to be processed and installed into Wine prefix on prefix update. Support for that has always been present for a long time and is still supported. However, we now allow Mono and Gecko to be installed globally. Wine can use the global instead of per-prefix installation, so those installation steps are skipped during prefix creation. To use that, you'd need to extract archives [1], [2] and [3] into the same place as you'd previously put MSI files.
