Hello,
I have an existing installer that I wrote in NSIS that does several things.
It installs the Adobe AIR runtime by invoking an executable provided by
Adobe. It then installs our AIR application, again using installation
utilities provided by Adobe. And finally, it installs media which our AIR
application knows where to find. This all works great. However, some of our
clients require a single MSI file so that they can do multiple installations
from a central location. I started playing with Wix in order to do this.
However, I have encountered the problem where it does not seem to be
possible to chain MSIs together. I was able to kinda get it working by
having a custom action invoke the AIR runtime installer using the code
below:
<CustomAction Id='InstallAIRRuntimeAction' FileKey='file_AIRInstaller_0'
ExeCommand='-silent' Return='asyncNoWait' />
<InstallExecuteSequence>
<Custom Action='InstallAIRRuntimeAction' After='InstallFinalize'>NOT
Installed</Custom>
</InstallExecuteSequence>
This works because the enclosing MSI doesn't wait for a response, and the
other MSI takes a few seconds to launch. This is of course very hacky. Is
there no way to do this properly? I don't mind if the two MSIs are not
chained, i.e. it would be O.K. if the AIR runtime remained on the machine
during an uninstall.
InstallShield advertises that they can chain MSIs. I would rather go the
extra mile and use Wix or something similar, rather than fork out $2000 for
InstallShield Professional. I'm suprised that Wix can't do the basic task of
calling another MSI given how low level it is when InstallShield is able to
do it. Am I missing something?
Thanks
Kevin
