Many thanks to all for replies,
yes XP is no longer supported as operating system but I work very well on it, I know that there is a time to upgrage it but at the moment I have no pc capable to run other operating systems like Win7, Win10, my pc is old, is an DELL Optilex GX620 Genuine Intel Dualcore 2.8 Ghz with 2GB of ram, so I need a new computer at all.
On my pc I have B4A 7.30 installed too and works well, I use B4R too but I've some problems because any time I compile it do a full compilation and require many time to compile, this not happen on Arduino IDE itself, it make a full compilation only a first time I compile, then recompile require just some seconds.
Here the problem seem to be related to 32-64 bit systems, not win XP itself, maybe on WinXP 64 bit the setup works.
Is there a way to download 7.32 release? I need to follow the changelog to find a download?
Many thanks
