What I meant GSX was working till now in the 32 bit system for your reference even with de icers. But there would some changes in the latest version because of which it's not working.
If with "latest version", you mean the one that updated to Couatl 3, then yes, there might have been several changes that might have an effect on 32 bit systems, but since nobody really use 32 bit OS with FSX anymore, we cannot test compatibility with such systems anymore.
You might try downloading and installing the VC++ 2013 redistributable runtimes, here:
