The program is freegate 7.16, the app itself will install a driver of its own, not a hardware driver, maybe a network filter. Just now, I tried to put the app under directory drive_c, and starts the app use command: wine start 'C:\fg716p.exe' Seems no previous error, but the driver still can't be installed. Any idea? Following is the end part of the log. fixme:advapi:CheckTokenMembership ((nil) 0x129b38 0x33ec30) stub! fixme:crypt:CertAddEncodedCTLToStore (0x12ab60, 00010001, 0x460000, 1666, 00000004, (nil)): stub fixme:crypt:CertAddEncodedCTLToStore (0x12ab60, 00010001, 0x12b390, 1169, 00000004, (nil)): stub fixme:crypt:CertEnumCTLsInStore (0x12ab60, (nil)): stub fixme:crypt:CertEnumCTLsInStore (0x12af40, (nil)): stub fixme:advapi:CheckTokenMembership ((nil) 0x122130 0x33f1a4) stub!
