Issue when registering 32bit COM from outside the system(SysWOW64) directory
Comment

When registering a 32-bit COM object from outside the system's SysWOW64
directory on a 64-bit Windows system, you may encounter issues due to the file system redirection and the registration process. Here's a workaround to address this problem:
Locate the Correct
Regsvr32
Executable:- On a 64-bit Windows system, there are two versions of the
regsvr32
executable: one in theSystem32
directory for 64-bit components and one in theSysWOW64
directory for 32-bit components. - To register a 32-bit COM object, you need to use the
regsvr32
executable located in theSysWOW64
directory. - Use the full path to the
regsvr32
executable in theSysWOW64
directory when registering the COM object.
- On a 64-bit Windows system, there are two versions of the
Use the Full Path to the COM DLL:
- Provide the full path to the 32-bit COM DLL when registering it.
- If the COM DLL is located outside the
SysWOW64
directory, include the full path to the DLL in theregsvr32
command.
Here's an example of registering a 32-bit COM object located outside the SysWOW64
directory:
batchC:\Windows\SysWOW64\regsvr32.exe "C:\Path\To\Your\32bit\COM.dll"
Make sure to replace "C:\Path\To\Your\32bit\COM.dll"
with the actual path to your 32-bit COM DLL.
By explicitly using the regsvr32
executable in the SysWOW64
directory and providing the full path to the COM DLL, you can register the 32-bit COM object successfully from outside the SysWOW64
directory on a 64-bit Windows system.
