--- Comment #21 from m0rvj johnpgoodman@gmail.com --- Hans Leidekker - I hope you don't mind me drawing this bug to your attention but it still applies in the latest version of wine, with the latest version of Logos Bible Software. I feel sure it must impact some other apps. The 'data' dir is empty in the msi and it overwrites to create an empty dir on linux. On windows it doesn't overwrite during updates so that downloaded data is preserved. There has to be a glitch in our implementation of msiexec or some file system issue? I wish I could figure it out!
