This is a tool for generating SxS manifests for Registration-Free COM (or "isolated" COM components) for native components. It is based on the original version by Cristian Adam available at https://www.codeproject.com/Articles/28682/regsvr42-Generate-SxS-Manifest-Files-from-Native-D

The basic usage is:

regsvr42 com.dll

which will generate a file named com.sxs.manifest. You can find out what interfaces and coclasses the COM DLL exports.

When used with a client application the usage is:

regsvr42 -client:client.exe com.dll

which will generate besides com.sxs.manifest another manifest file named client.exe.manifest. If client.exe already has a manifest file embedded, the contents of that manifest file are preserved into client.exe.manifest alongside with the reference to com.sxs assembly.

If you have more than one COM DLLs you want to use can use the tool in batch mode like:

regsvr42 -client:client.exe -batch:file_containing_com_dll_file_names

You can put all the COM DLLs inside one directory and there will be just one manifest file inside the directory named directory_name.manifest

regsvr42 -client:client.exe -dir:directory_with_com_dlls

If you have more than one directories with COM DLLs you can use the -batch function with all the names of the directories written in the batch file.

regsvr42 -client:client.exe -batch:file_containing_directory_names
