For most NSIS-based applications I do not even bother about previously removing 
the old version as most installers handle "upgrades" correctly if there is 
already a version of the software installed.

Just for real remove it's often headache. But the script I posted helps in many 
cases as the uninstaller forks and then removes itself at the end. So waiting 
for it to disappear is usually fine.
