The program is checking, for an unknown reason, that C: is an NTFS partition. I haven’t found how I can convince him that it’s well the case.
It checks for at least these flags from the call to GetVolumeInformation:
FILE_PERSISTENT_ACLS | FILE_NAMED_STREAMS | FILE_SUPPORTS_OBJECT_IDS
Wine does not set them because none of them are supported. You can hack Wine to return those flags set:
dlls/kernel32/volume.c:625
if (flags) *flags = FILE_CASE_PRESERVED_NAMES | FILE_PERSISTENT_ACLS | FILE_NAMED_STREAMS | FILE_SUPPORTS_OBJECT_IDS;
It triggers wine_gecko install and asks to install msxml6 and appears to ask for server authentication. You might have to kill it few times before it runs.
