Hi,
Now I come to the uninstall part.
When install my product, I have a bootstrapper, that install an external
product first as the prerequisite, and then invoke my own MSI. When uninstall
my product, I also need to uninstall the external product after uninstall my
MSI.
The command I used to uninstall the external product is
msiexec.exe /q /i {THE-GUID-OF-EXTERNAL_PRODUCT} param1=blabla param2=blabla
lotsofparams...
I don't want user to be aware of the external product. If the uninstall of
external product fails, no need to rollback, show a warning or log the failure
would be fine but it's not a hard requirement.
I cannot put the command as a CustomAction, even set the
CustomAction/@Return=asyncNoWait, because my own msi might have not exit yet
when the new one runs.
I'm thinking about have a script which will install my product first and then
uninstall the external product (the bootstrapper for uninstallation), but since
shortcut at start menu for uninstallation is not recommended, how could I let
user remember to use the script to uninstall? Besides, how could I delete the
script itself during uninstall?
I cannot change the UninstallString registry value of ARP, because it's
determined and set by Windows Installer and not opened for customization.
Is the ARPSYSTEMCOMPONENT the only solution for this scenario? Or are there any
other better approaches?
Thanks,
-Elfe
