this EXE was compiles for the x64 architecture

Question

I developed a Flutter application and used Inno Setup to create an installer for it. The installer seems to work fine, and the installation process completes without any issues. However, when I try to run the installed application, I encounter the following error message:

"This EXE was compiles for the x64 architecture."

Below is the debug log which i could see when installing and running the application in inno setup script
