interaction, an autoIt-script combined with the uninstall routine might do the job. The
uninstall statement can be embedded in a [winbatch] section of the wInst-script:
[Winbatch_start_ThunderbirdUninstall]
%SYSTEMROOT%\UninstallThunderbird.exe /ma
When using an uninstall program, it always should be tested whether all of the files
have been deleted and the computer is still in a stable state.
Products which are installed by MSI often come also with an uninstall option, which
usually is the msiexec.exe parameter /x. And the parameter /qb-! is for
unattended mode (without user interaction). So this is the statement for unattended
deinstall:
msiexec.exe /x myPacket.msi /qb-!
Instead of the package name you could also use the GUID (Global Unique ID) with
msiexec.exe. This GUID identifies the product in the system and can be found in the
registry directory
HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall
A request using the GUID looks like this:
msiexec.exe /x {003C5074-EB37-4A75-AC4B-F5394E08B4DD} /qb-!
If none of these methods is available or sufficient, the deinstallation can be done by a
wInst-script as described in the following:
4.3.1.8.2. Useful wInst commands for uninstall
If a product has been installed by wInst functions, or if there is no uninstall routine for
the product, the complete deinstallation has to be done by a wInst script. WInst comes
with some powerful uninstall functions. In this chapter we will have an overview, for
detailed information refer to the wInst handbook.
