Ok. I just wanted to make sure, because it is a common error.

True. You can create a feature request.

Still no proper wince compiler.

Unix?
Maybe you set the wrong Target OS in the compiler options?

Note: Leave the Target OS/CPU in the package compiler options empty,  
so that it uses the Target OS/CPU form the project.

Can you create create a bug report and attach it? I'm sure that  
Felipe, the main maintainer of the wince widgetset will take a look  
soon.

What do you mean with 'install'?

Normally 'installing a package' means to compile a new IDE with the  
package compiled into it. Because the IDE can not run under wince you  
can not "install" a package for wince.

As far as I know Felipe has not changed the installation process. I  
have not tried myself.

Felipe, can you update the page for 0.9.28?
