The Wow64 Parameter in Package.ini for ThinApp (1021314)
Wow64 is a new Package.ini parameter for ThinApp 4.0.2.
The Wow64 parameter helps to run 32‐bit applications on a 64‐bit Windows operating system.
A 32-bit application "asks" the operating system if it is 64- or 32-bit.
If you don’t set Wow64, the application gets an honest answer from the operating system: if the operating system is 64-bit, it says so.
Generally, 32-bit applications can run on 64-bit operating systems, so you don’t need this Wow64 setting.
[BuildOptions];Wow64=0Wow64 is commented out, so not set. The operating system tells the application the truth about whether it is 32-bit or 64-bit.
[BuildOptions]Wow64=0 (0=No, I am not a 64-bit operating system; I am 32-bit)A 64-bit operating system tells a lie about itself. It describes itself to the application as 32-bit. The 64-bit operating system is emulating a 32-bit operating system. A 32-bit operating system also tells the application that it is 32-bit, but this is not a lie.
[BuildOptions]Wow64=1 (1=Yes, I am a 64-bit operating system)A 32-bit operating system tells a lie about itself. It describes itself to the application as 64-bit. The 32-bit operating system is emulating a 64-bit operating system. A 64-bit operating system also tells the application that it is 64-bit, but this is not a lie.
