--- Comment #1 from Rainer Schuetze <r.sagitario at gmx.de> ---
I tried to reproduce this, but for me, the uninstaller is blocking the
installer until it is finished. The NSIS script is using an ExecWait statement
to run the uninstaller.

Maybe ExecWait doesn't work for some reason. What Windows version are you
running? Mine is Win 10 1903. What version are you uninstalling?
