Ansys Fluent 2025R1 udf.bat does not detect MSVC 2022 build tools

  When attempting to set up a UDF compilation environment for Fluent 2025R1 using Build Tools for Visual Studio 2022 on Windows 11, udf.bat looks at the wrong directory. In a fresh installation of the latest MSVC Build Tools and Ansys Student (installed to default locations), udf.bat looks at the following location (taken from $(FLUENT_ROOT)\$(ARCH)\udf.bat, line 13):
```
set MSVC_DEFAULT=%ProgramFiles%\Microsoft Visual Studio\2022
```
  However, Build Tools does not install to Program Files, but rather Program Files (x86). Changing the line to the following allows detection of the MSVC compiler by the script:
```
set MSVC_DEFAULT=%ProgramFiles(x86)%\Microsoft Visual Studio\2022
```
  I do not know if this is a regression from previous versions of Fluent or if the VS IDE installs to %ProgramFiles% by default, but I wanted to report this as a potential bug. This is the only forum I have access to, so please let me know if there is a more appropriate location I can report this to.
