Conditionally installing files for x86 and x64

[rmarma]

I have some C++ files that are processor architecture dependent, i.e. if the processor is 32 bit, I need to install a set of files and if the processor is 64 bit I need to install another set of files.

Can you advise how to do that?

Definitely.

You can use the Get System Settings command and select the Is Windows 64 Bit capability.
Then, use an If.. Else.. End block to control the flow of your installer accordingly.

In fact, you can create a setup from the Win64 Setup template, and it will show you exactly how this is done.

Thank you for the quick reply.
I'm totally new to InstallAware and am finding the MSICode quite hard to read.

Any chance you could give me an example on how to conditionally install to the TARGETDIR a file called Test.dll.

[giaviv]

Sure!


Get System Setting Windows in 64 bit Mode into ISWINDOWS64BIT
if Variable ISWINDOWS64BIT Equals
Install Files somefolder\Test.dll to $TARGETDIR$
else
Install Files somefolder\Test_x86.dll to $TARGETDIR$
end



Or paste this in your IA IDE:

Thank you.

Another related question.

In the MSI Code, I have the following line:

Set x64 = Native 64 bit Windows, AMD64 and EMT64T Architecture - installation mode

When I install on a 64 bit OS, I was expecting the TARGETDIR to resolve to C:\Program Files however it is resolving to C:\Program Files (x86).

How do I configure the TARGETDIR appropriately on 64 bit?

This is the MSICode I added:

Get System Setting Windows in 64 bit Mode into ISWINDOWS64BIT
if Variable ISWINDOWS64BIT Equals TRUE
Set x64 - Native 64 bit Windows, AMD64 and EM64T Architectures - installation mode
end

Hi,

Please create a setup using the Win64 Setup template.
Go over the MSIcode there, specifically the Define Setup Globals Region, and see how it is done there. Let me know if you have any questions!

[rmarma]

Got it.
