Some other trigger a disinstallation of previous version and an<br>
installation of the newer ones, while the disinstallation suffer from<br>
the classical ''fork'' problem of NSIS.<br>
Symptoms are that WPKG say ''check failed after upgrade'' but software<br>
are correctly installed (because the installation continue in<br>
background, and normally works).<br>

Normally i solve that situation doing, on upgrade, a disinstallation of<br>
the previous one in a start "" /wait jail (with or without the _?<br>
option, it depends), and then an installation.<br>

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.<br>
<br>
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.<br>
