Hum. I have a *Win7 x64* with Lazarus 1.0.10 installed ready for cross 
compilation for
and  it works. What did I do ?

Install process

Install fpc-2.6.2.i386-win32.exe
     - C:\fpc\2.6.2
     - full install
     - do not associate.pp, .inc etc

Install fpc-2.6.2.arm-wince.exe
     - C:\fpc\2.6.2
     - fpc folder exists: OK
     - full install
     - do not associate.pp, .inc etc

Install fpc-2.6.2.x86_64-win64.exe
     - C:\fpc\2.6.2
     - fpc folder exists: OK
     - full install
     - do not associate.pp, .inc etc

Download fpc 2.6.2 sources (fpcbuild-2.6.2.zip), decompress and move into

Install Lazarus lazarus-1.0.10-fpc-2.6.2-win64.exe as usual
     - C:\Lazarus
     - full install

     - adapt fpc compiler and fpc sources paths on first launch screen
     - config IDE to your needs
     - rename or delete C:\Lazarus\fpc as it bacame useless

Recompile packages and projects as needed
I've made a very little test program (main form, a close button) and it 
works on the three platforms
To be fully honest I've not yet tried to build complex projects. But 
I'll do it and let you know wkat happens
