Hi,

I am upgrading 3 versions , lets say a,b,c while installing the product "D" . Is there any way that msi "D" can cotrol the installation sequence of upgardes a, b, c.
What i meant is application should upgrade "c 1st" and then "b next" and then "c".
by default it is uninstalling "a , b then c".
please send the response.

Thanks,
R.Joseph.

I can't think of any way that you could control the order but then neither can I think of a reason why one would need to. If a component needs to be upgraded, it'll be upgraded: why does the order matter?

Hi ,

Thanks for your quick response.

Vendor has created three msi's and included some customactions and those are already there in live environment.They gave some sequence to uninstall , other wise it will throw some errors becuase of vb script customactions.Thats the reason we need to upgrade in that sequence only.

you might have to script the uninstalls outside your actual MSI.
As in a VBS or something calling sequential MSIEXEC /x 's

Also, call the vendor and yell at them.

You need to be careful with your terminology, since a Windows Installer "upgrade" covers a scenario where an MSI will perform (what I call) an "in-place" upgrade, i.e. the package contains all the information it needs to upgrade all the components of a version (or several versions) of a product.

As Pieter points out, you're probably going to have to script the uninstallation sequence. Use some intelligent script, like VBS, so that you determine the success of a step before you progress to the next one.
