Difference between msiexec and a Double Click

We are working with Acrobat Pro 9.x. Since this is a huge app it does take a long time to install. But we have noticed something odd.

If we double click on the AcroPro.Msi file it will look for (and in our case find) Acrobat Pro 8.x. It uninstalls this and then installs v9.x

If we run the following command:
msiexec /i "%path%\AcroPro.msi" /qb! TRNASFORMS="%path%\AcroPro.mst" REBOOT=R

It takes "Twice" as long to run and do the same stuff.

This is all on Windows XP. Is there a difference between launching a MSI by double clicking on it Vs. calling Msiexec to run it? Is the msiexec.exe method doing something like reading more data that causes it to run slower?

We have performed this test on at least 4 differnet XP machines and the resuts are the same each time......calling this MSI from a command line takes twice as long.

When you double click it runs the "user interface" sequence which isn't run when installing silently. You can set conditions in the MSI to only run during certain sequences, so it's possible that there's more jazz happening when it's silent. It would take a lot of digging to find out what.

It's also not running your transform when you double click.

I hope you didn't copy/paste that command line because it's way wrong. [:D]
