如何使用C＃使用Registry查找软件的安装位置

Question

I'm a beginner to Registry keys, and
I want to find out the installed location of AutoCAD software which have the higher version of it using C#.
More than one AutoCAD may get installed on a computer(AutoCAD 2012, AutoCAD 2014, etc), I want to get higher version alone., (result will be path of AutoCAD 2014(acad.exe))

And also have to find out acCoreConsole.exe file isExist on the path found in previous result..

I can't browse through the location of Registry.,

HKEY_LOCAL_MACHINE\Software\Autodesk\AutoCAD\R18.2\ACAD-D001:409\AcadLocation

I tried this code:

Registry.LocalMachine.OpenSubKey("Software\\Autodesk\\AutoCAD", false).GetSubKeyNames();

But this leads to somewhere else:

HKEY_LOCAL_MACHINE\\Software\\Wow6432Node\\Autodesk\\ADSKAssetLibrary

I don't know how to get the location of acad.exe., I'm using 64 bit machine. Any help would be appreciateable., Please do the needful, Thanks,

Answer 1

Your application is most likely running 32 bit, because it seems like you get autoredirected to WoW6432Node which is the default directory for 32 bit applications.

Try this code:

RegistryKey.OpenBaseKey(RegistryHive.LocalMachine, RegistryView.Registry64).OpenSubKey(@"your path here", false);

I'm pretty sure you run a 32 bit app on a 64 bit machine, I've had this problem before as well

EDIT: Forgot to append the last part of your command, but you can just append it I guess
