Some other trigger a disinstallation of previous version and an
installation of the newer ones, while the disinstallation suffer from
the classical ''fork'' problem of NSIS.
Symptoms are that WPKG say ''check failed after upgrade'' but software
are correctly installed (because the installation continue in
background, and normally works).
Normally i solve that situation doing, on upgrade, a disinstallation of
the previous one in a start "" /wait jail (with or without the _?
option, it depends), and then an installation.
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.
