The compilation process was changed in this version.
If you are asked to find a file named ilasm.exe then your computer is probably not installed with .Net Framework 1.1.
Press cancel and install it:
http://www.microsoft.com/downloads/d...DisplayLang=en
Do not use other versions of ilasm.exe as it will not work properly.
Basic4ppc copies ilasm.exe to its own folder: c:\Program Files\Anywhere Software\Basic4ppc Desktop
So if you've already found a wrong version of ilasm.exe then you should delete it from Basic4ppc folder to allow it to find the right version.
