Welcome in club "I am using Linux and I can't save on a directory not created for/by the wine user" (probably your fat directory belongs to root (/irony))
This is not a bug and will be closed with WON'TFIX quicker than you can read this. This is a feature for the time being as I read from another bug.
Sure... I can create a new directory in Total Commander on FAT32 partition, I can copy file from one directory to another, I can delete files from this partition, but I can't install stupid game/program because installer isn't working fine... Yes... partition belongs to root but other groups HAVE a read,write,execute permissions...
