DicomObjects.COM 64bit Registration

This article provides help for those wishing to use the 64 bit version of DicomObjects from Visual Studio (for development in any supported language, including C# or C++)

Visual Studio is itself a 32 bit application, even when it is compiling a 64 bit application, which uses a 64 bit OCX. Therefore, it cannot ITSELF access the 64 bit OCX for intellisense, #import etc.  The standard requirements for using 64 bit COM component in Visual Studio is that a 32 bit version with the same interfaces must be registered on the development machine (this is not of course needed for subsequent execution).

32 bit Registration

C:\Windows\SysWOW64\regsvr32.exe  \DicomObjects.8.32.xx.yy.ocx

64 bit Registration

C:\Windows\System32\regsvr32.exe   \DicomObjects.8.64.xx.yy.ocx
