it's the latter, I'm trying to install a program to another partition, which just happens to be a FAT32 partition.
I'm uncertain about what to do next, since a WINEDEBUG=+all kinda generates too much information and makes stuff not work.
If you think Wine is to blame, find the last known version of Wine that successfully installs your programs to fat32 then run a regression test. http://wiki.winehq.org/RegressionTesting
