Hi folks,

I am trying to read the installation path using a VB Script. In fact, I
can already do that easily by using the script and the
"CustomActionData" property. The problem I have is that this
CustomAction is supposed to run between InstallInitialize and
InstallFinalize in the InstallExecuteSequence table.

I need this script to run before InstallInitialize. Anything later than
that is simply too late for me(the changes that I make to the .msi are
ignored). If I change the sequence and put it before InstallInitialize I
get an error.

Does anyone know how I could get the installation path before
InstallInitialize runs ? Please help. Thanks.

You'd need to make it an immediate custom action instead of deferred (take
1024, msidbCustomActionTypeInScript, out of the Type), then you can sequence
it early in the execute sequence, if that works for you. You won't need
CustomActionData if it's immediate, just use the TARGETDIR property.

Thanks Phil for taking your time and answering me.

I understand the part about not using deferred custom actions. I don't
have 1024 as a Type though. The .NET installer created automatically two
rows for my script in CustomAction, Type 51 and 5xx(something like this,
I don't have it here right now).

Now, I have another script, and I set it up with Orca (manually, not
through the .NET installer project) to a CustomAction Type 6(VB Script).
I can put it pretty much wherever I want in the InstallExecuteSequence
table and have it run in the beginning of the installation.

What I wasn't able to figure out was how to read the installation path

:-( I tried MsgBox ("TARGETDIR") and loads of other things which I

thought would return the path. I still couldn't find the right
parameters/syntax. When I read what you say I imagine it should be
fairly easy. Not for me, at least not yet...

I would really appreciate if you could shed a little bit more light on
this one. Thanks a lot

In a VBScript you need to say Msgbox (Property("TARGETDIR"))

I am trying just to get the path that the user enters or the default path in my install MSI and pass it to a script that then moves a file from that path to another path. I want to use a VB Script but I do not know what to pass in the custom action or how to access it in using a VB Script. I am a technical writer using Visual Studio to create a Help Project so I do not know some of the ins and out of custom actions and VB script. Any help would be appreciated.

Thanks,

Ross Stanek
