显示驱动程序文件-hdi-已丢失或损坏解决

关于AutoCAD2014x64安装后打开提示“显示驱动程序文件hdi已丢失或损坏”的解决很多朋友在Windows7、Windows8、Windows8.1x64系统下安装AutoCAD2014x64时都会出现“显示驱动程序文件（.hdi）已丢失或损坏，程序将关闭。”这个问题，都很郁闷，试过很多方法，尝试过卸载再重新安装，但是问题还是不能解决。在网上也有些朋友说是这与DirectX9.0c、DirectX11有关，但是我一直没能在Microsoft官网下载到DirectX11去测试，所以也就不做评价，希望有人尝试过能够把尝试经历发布出来供大家分享（至于成功与否无关紧要）。在这里我就简单写写我尝试经验吧。1.我首先关注的是提示中的路径“D:\ProgramFiles\AutoCAD2014\Drv\”，找到目录看了一下，基本上全部都是*.hdi文件，看不大明白；2.我想了想会不会出现在注册表中，于是道注册表中查找。在“运行”输入“Regedit”打开注册表编辑器，“Ctrl+F”查找“D:\ProgramFiles\AutoCAD2014\Drv\”与之相关的注册表项，看看到底是什么东西。（1）在[HKEY_CURRENT_USER\Software\Autodesk\AutoCAD\R19.1\ACAD-D001:804\3DGSConfiguration]注册表项中存在“CustomHeidiDriverPath”，其键值为“D:\ProgramFiles\AutoCAD2014\Drv\”；（2）在[HKEY_LOCAL_MACHINE\SOFTWARE\Autodesk\AutoCAD\R19.1\ACAD-D001:804\3DGSConfiguration]和[HKEY_LOCAL_MACHINE\SOFTWARE\Autodesk\AutoCAD\R19.1\ACAD-D001:804\3DGSConfiguration\GSHEIDI10]注册表项中均有“CustomHeidiDriverPath”，且其键值为“D:\ProgramFiles\AutoCAD2014\Drv\”尝试同时将其改名，退出注册表编辑器，再打开AutoCAD2014成功。（注意：尝试之前最好先将注册表导出备份，以防修改出错）或者将下面三段文字复制到记事本，另存为“xx.reg”文件，直接双击导入注册表即可完成操作。（双横线是分界线）001.regWindowsRegistryEditorVersion5.00[HKEY_CURRENT_USER\Software\Autodesk\AutoCAD\R19.1\ACAD-D001:804\3DGSConfiguration]Help=FramesPerSecond=dword:00000005ContextHelp=CustomHeidiDriver=acaddm11.hdiSurfaceTessellationTol=dword:0000005cFlags=dword:00082602CurveTessellationTol=dword:00000057MaxTessellations=dword:00000006FailureStatus=dword:00000000ProblemState=dword:00000000FirstRun=dword:00000001DegradationChainOrder=hex:01,00,00,80,02,00,00,80,03,00,00,80,04,00,00,80,05,\00,00,80,06,00,00,80,07,00,00,80,08,00,00,80,09,00,00,80,0a,00,00,80,00,00,\00,80,0b,00,00,80,0c,00,00,80,0d,00,00,80,0e,00,00,80,0f,00,00,80,10,00,00,\80,11,00,00,80FeatureData=hex:0a,00,00,00,00,00,00,00,01,00,00,00TunningDate=2013/11/30PTXMLVersion=19.1.0.02PTCardName=Intel(R)HDGraphics4600PTDriverName=9.18.0013.3165PTCardManufacturer=Intel(R)PTChipType=HDGraphics4600PTCardID=dword:00000416PTManufacturerID=dword:00008086PTCardMemory=1696PTDriver=dword:00000002PTRejectDriver=dword:00000004PTCardCertified=dword:00000000PTDriverMatch=dword:00000000PTCardAvaliable=dword:00000001PTCardRecomended=dword:00000001PTWorkArounds=12:DefaultDriverXP64,6.14.0001.001;SZB:DefaultDriverXP,6.14.0001.001;SZB:DefaultDriverwin764,8.15.10.00001;DM:DefaultDriverwin7,8.15.10.00001;SZB:DefaultDriverVista64,7.15.0010.001;SZB:DefaultDriverVista,7.15.0010.001;SZB:DefaultDriverXP64,6.14.0001.001;SZB:DefaultDriverXP,6.14.0001.001;SZB:DefaultDriverwin764,8.15.10.00001;DM:DefaultDriverwin7,8.15.10.00001;SZB:DefaultDriverVista64,7.15.0010.001;SZB:DefaultDriverVista,7.15.0010.001;SZB:LastTuningDBModificationTime=hex:80,a2,10,64,82,fd,cd,01LastRemoteDesktop=dword:00000000LastCardVendor=dword:00008086LastCardDevice=dword:00000416LastDriverLo=dword:000d0c5dLastDriverHi=dword:00090012SNAPSHOTFLAGS=dword:000025b6SNAPSHOTCACHETESS=dword:00000006SNAPSHOTCURVTESS=dword:00000057SNAPSHOTSURFTESS=dword:0000005cSNAPSHOTTRANSPARENCY=dword:00000001SNAPSHOTDRIVER=AcadDM11.hdiCustomHeidiDriverPath000=D:\\ProgramFiles\\AutoCAD2014\\Drv\\002.regWindowsRegistryEditorVersion5.00[HKEY_LOCAL_MACHINE\SOFTWARE\Autodesk\AutoCAD\R19.1\ACAD-D001:804\3DGSConfiguration]Flags=dword:00000000CertificationSPVersion=0CustomHeidiDriver=AcadDM11.hdiPath=D:\\ProgramFiles\\AutoCAD2014\\\\acgs.dllCurrentGS=GSCustomHeidiDriverPath000=D:\\ProgramFiles\\AutoCAD2014\\Drv\\[HKEY_LOCAL_MACHINE\SOFTWARE\Autodesk\AutoCAD\R19.1\ACAD-D001:804\3DGSConfiguration\GSHEIDI10]Flags=dword:00000020CustomHeidiDriver=AcadDM10.hdiCustomHeidiDriverPath000=D:\\ProgramFiles\\AutoCAD2014\\Drv\\003.regWindowsRegistryEditorVersion5.00[HKEY_LOCAL_MACHINE\SOFTWARE\Autodesk\AutoCAD\R19.1\ACAD-D001:804\3DGSConfiguration\GSHEIDI10]Flags=dword:00000020CustomHeidiDriver=AcadDM10.hdiCustomHeidiDriverPath000=D:\\ProgramFiles\\AutoCAD2014\\Drv\\
