Searched and seems nobody else ran into this yet. Almost finished with STEP extended installation, but I'm getting an error now when running TES5Edit: [spoiler=bug report]date/time : 2015-06-28, 23:55:29, 335ms operating system : Windows 7 x64 Service Pack 1 build 7601 system language : English program up time : 5 minutes 38 seconds processors : 8x Intel® Core i7-4790K CPU @ 4.00GHz physical memory : 27369/32648 MB (free/total) free disk space : (C:) 146.16 GB (D:) 2882.79 GB display mode : 3840x2160, 32 bit process id : $18c0 allocated memory : 880.97 MB command line : "D:\Games\Steam\steamapps\common\Skyrim\TES5Edit_3_1_1\TES5Edit.exe" -o:'D:\TES5LODGenOutput executable : TES5Edit.exe exec. date/time : 2015-05-19 04:41 version : 3.1.1.0 compiled with : Delphi XE madExcept version : 4.0.5 callstack crc : $35a1790b, $29bc6337, $d5572bee exception number : 1 exception class : Exception exception message : Unable to create destination directory 'D:\TES5LODGenOutput\DynDOLOD-temp\textures\effects\. main thread ($ed0): 007231ac +13c TES5Edit.exe wbBSA 299 +27 TwbContainerHandler.ResourceCopy 00a195d5 +059 TES5Edit.exe wbScriptAdapter 1443 +1 IwbContainerHandler_ResourceCopy 009a638a +09e TES5Edit.exe JvInterpreter GetFun 009a6ae3 +28b TES5Edit.exe JvInterpreter TJvInterpreterAdapter.GetValue 009aa8a8 +064 TES5Edit.exe JvInterpreter TJvInterpreterExpression.GetValue 009ab4d1 +09d TES5Edit.exe JvInterpreter TJvInterpreterFunction.GetValue 009af45c +01c TES5Edit.exe JvInterpreter TJvInterpreterUnit.GetValue 009a9e9c +164 TES5Edit.exe JvInterpreter TJvInterpreterExpression.InternalGetValue 009ac30d +05d TES5Edit.exe JvInterpreter TJvInterpreterFunction.InterpretIdentifier 009ab675 +0e5 TES5Edit.exe JvInterpreter TJvInterpreterFunction.InterpretStatement 009ac504 +054 TES5Edit.exe JvInterpreter TJvInterpreterFunction.InterpretIf 009ab6c5 +135 TES5Edit.exe JvInterpreter TJvInterpreterFunction.InterpretStatement 009ac445 +0b1 TES5Edit.exe JvInterpreter TJvInterpreterFunction.InterpretBegin 009ab6bc +12c TES5Edit.exe JvInterpreter TJvInterpreterFunction.InterpretStatement 009aca33 +1b3 TES5Edit.exe JvInterpreter TJvInterpreterFunction.InterpretFor 009ab6e0 +150 TES5Edit.exe JvInterpreter TJvInterpreterFunction.InterpretStatement 009ac445 +0b1 TES5Edit.exe JvInterpreter TJvInterpreterFunction.InterpretBegin 009ab30e +052 TES5Edit.exe JvInterpreter TJvInterpreterFunction.InFunction 009af853 +0c3 TES5Edit.exe JvInterpreter TJvInterpreterUnit.ExecFunction 009afb01 +145 TES5Edit.exe JvInterpreter TJvInterpreterUnit.CallFunctionEx 009af982 +062 TES5Edit.exe JvInterpreter TJvInterpreterUnit.CallFunction 00a5e89e +226 TES5Edit.exe frmViewMain 6899 +43 TfrmMain.ApplyScript 00a5f27c +104 TES5Edit.exe frmViewMain 6998 +13 TfrmMain.mniNavApplyScriptClick 00525e97 +0a7 TES5Edit.exe Menus TMenuItem.Click 00527393 +013 TES5Edit.exe Menus TMenu.DispatchCommand 00528572 +082 TES5Edit.exe Menus TPopupList.WndProc 005284c1 +01d TES5Edit.exe Menus TPopupList.MainWndProc 004c4e8c +014 TES5Edit.exe Classes StdWndProc 773f7885 +00a USER32.dll DispatchMessageW 005b2133 +0f3 TES5Edit.exe Forms TApplication.ProcessMessage 005b2176 +00a TES5Edit.exe Forms TApplication.HandleMessage 005b24a1 +0c9 TES5Edit.exe Forms TApplication.Run 00a8ffaf +05f TES5Edit.exe TES5Edit 77 +7 initialization 772c3378 +010 kernel32.dll BaseThreadInitThunk thread $e50 (TWorkerThread): 7795f916 +0e ntdll.dll NtWaitForSingleObject 75b614a5 +92 KERNELBASE.dll WaitForSingleObjectEx 772c118f +3e kernel32.dll WaitForSingleObjectEx 772c1143 +0d kernel32.dll WaitForSingleObject 005d21e9 +19 TES5Edit.exe VirtualTrees 6308 +3 TWorkerThread.Execute 00472cf7 +2b TES5Edit.exe madExcept HookedTThreadExecute 004c21c6 +42 TES5Edit.exe Classes ThreadProc 00407588 +28 TES5Edit.exe System 148 +0 ThreadWrapper 00472bd9 +0d TES5Edit.exe madExcept CallThreadProcSafe 00472c43 +37 TES5Edit.exe madExcept ThreadExceptFrame 772c3378 +10 kernel32.dll BaseThreadInitThunk >> created by main thread ($ed0) at: 005d20d1 +19 TES5Edit.exe VirtualTrees 6251 +1 TWorkerThread.Create thread $16e4: 779601a2 +0e ntdll.dll NtWaitForMultipleObjects 772c3378 +10 kernel32.dll BaseThreadInitThunk thread $1338: 77961f8b +0b ntdll.dll NtWaitForWorkViaWorkerFactory 772c3378 +10 kernel32.dll BaseThreadInitThunk thread $1318: 77961f8b +0b ntdll.dll NtWaitForWorkViaWorkerFactory 772c3378 +10 kernel32.dll BaseThreadInitThunk thread $1868: 77961f8b +0b ntdll.dll NtWaitForWorkViaWorkerFactory 772c3378 +10 kernel32.dll BaseThreadInitThunk - Initially had "-o" set to default directory (C:\), but moved to D:\ and set permissions to full control for user (admin) thinking it was a permissions issue. Same result, but where the exception number was "3" initially it is now "1" as in above bug report - tried setting MO, TES5Edit, and the LODGen apps to "run as administrator" with same result Note: steam installation must stay on D drive and can't be moved to C Any suggestions on what to try next?
