--- Comment #3 from ebemacc+bugreport@gmail.com --- The problem is caused by wineserver supporting registry operations at 100-nanoseconds FILETIME granularity at runtime, but storing registry key modification dates at 1-second unix time granularity on disk, thereby effectively zeroing all sub-second time information.
IVONA Voices store checksums of their installation dates in obfuscated registry keys using 100-nanoseconds granularity, but on subsequent runs, once the original wineserver session has ended, recalculate and compare these checksums from the registry key modification dates now effectively using 1-second granularity. The checksums differ and IVONA Voices refuse to load.
