does anybody know how can i add some executables through custom action (not as prerequisites). In all cases i have checked, i always got errors like: another installation is in progress or the exe are not applied at all. I have not found any solution in the related posts in the forum.
Please help me becasue i have lost so much time to find a solution for this and everything that i use have failed.:(
Windows Installer will allow only one installer execute sequence to run at a time, so you cannot run another MSI installation from the Execute sequence of an MSI.
You should be able to do this with an immediate custom action in the Install sequence, before ExecuteAction, since it is ExecuteAction that initiates the Execute sequence.
You should also note that doing this will result in a custom action that will not execute during a silent install, and is really not a Best Practice, since the Install sequence should ideally not make any changes to the system.
(There really isn't a GOOD way to run an MSI from another MSI except by using chained MSIs.)
Thanks Kathy. You have absolutely right. It's not a good idea to run an msi from another msi. I try this and there are so many missmatches 😞 ... I think that if this was able to happen it will be most welcomed for many people.
