InstallAware

Using InstallAware Studio Admin X9, I have a project that requires the Microsoft .NET Framework 4.7.2. It appears that the script Check_for_Microsoft_.NET_Framework_4.7.2_(x86_and_x64) may set the processor architecture to 32 bit, even when environment is actually 64-bit Windows 10?

Scenario:

-At the top of my project's main MSIcode script, I set mode as 64 Bit Mode:

Set x64 - Native 64 bit Windows, AMD64, EM64T, and ARM64 Achitectures - installation mode

-Later in project's script, call is made to the script Check_for_Microsoft_.NET_Framework_4.7.2_(x86_and_x64).

-It appears to me that when control returns from the script Check_for_Microsoft_.NET_Framework_4.7.2_(x86_and_x64), when installation performed on a Windows 10 machine (64 bit operating system), that the project's main script then interprets the environment as 32 bit.

For example, Get Folder Location System->Program Files Directory into PROGRAMFILES returns 32-bit program files location 'C:\Program Files (x86)', rather than Windows 10 64-bit program files directory 'C:\Program Files\'.

-Perhaps the incorrect variable is being referenced, line 19 below, test for ISWINDOWS64BIT? That being true on Windows 10 (64 bit operating system), then line 20 does a Set Win32...?

It's correct to check for 64 bit at very beginning of the man script. You may also switch to 64 bit just after, in case you need to execute a command which depends on x64 mode settings.

However, it's a good practice to switch to x64 mode or to include an additional x64 mode switch also, within the "[Define Setup Globals] Region". This because "Application Runtime scripts" (if present) may revert back to x32 bit mode.

-Perhaps the incorrect variable is being referenced, line 19 below, test for ISWINDOWS64BIT? That being true on Windows 10 (64 bit operating system), then line 20 does a Set Win32...?

No, this is not an error. Here the script has to detect the location of the "C:\Windows\SysWOW64". This system folder only exists on x64 systems and this can be only accessed when the process runs in 32 bit mode.
