Why is that? The reason is that you look at 32-bit, where technical limitations force us to hard-code a certain base address for all of the includede MSYS2 .dll files (i.e. all libraries that require, or implement, the POSIX emulation layer called MSYS2). To avoid clashes with other .dll files, that base address is adjusted via the post-install.bat script for your particular environment. If you want to avoid that, you will have to extract the installer via 7-Zip: it is a self-extracting .7z archive (and the self-extractor automatically executes post-install.bat, which subsequently deletes itself). Ciao, Johannes
