* Improve Windows installer
1. We now show a welcome page before starting the installation.
2. The installer now has an icon.
3. We show a finish page after installation has completed.
4. We detect existing suggestions and abort while mentioning
"daml install latest".
* Ask if existing installation should be removed
ExecWait will run the command in a new terminal which looks fairly
ugly and also makes it impossible to see what has been written to that
terminal since it closes automatically. nsexec::ExecToLog on the other
hand will write to the standard log Window in the installer which
seems much nicer.
It turns out my suspicion that the tar plugin was the thing that
messed up paths was completely correct. However, I messed up the PATH
to daml which resulted in me still running the old binary.
I’ve fixed the path and also moved to a temporary
directory (PLUGINSDIR seems like the easiest option for that) so that
things are cleaned up automatically by nsis.
