Running (Dar)Wine 1.1.2 I am attempting to run a program which uses Rijndael to decrypt passwords stored in a text file. The program uses a popular VB port of CRijndael which uses RtlMoveMemory in Kernel32.dll. Upon apparent decryption I do not get the same results as the windows version which causes an error in my application. Here is a portion of output from Dependency Walker. Code: GetProcAddress(0x7B810000 [c:\windows\system32\KERNEL32.DLL], "RtlMoveMemory") called from "c:\windows\system32\MSVBVM60.DLL" at address 0x6600A0D8 and returned 0x7BC54758 by thread 1. First chance exception 0xC000008F (Float Inexact Result) occurred in "c:\windows\system32\KERNEL32.DLL" at address 0x7B8334B3 by thread 1. Is there anything I can do? Is this the right place?
