Can I register my bundled DLLs with regsvr32.exe?

Sorry but bundled DLLs cannot be registered via "regsvr32.exe". Bundled DLLs are only visible for the protected application. As you can see, "regsvr32.exe" is an external process and won't be able to see the bundled DLLs.

Please, go to the XBundler panel, check the option "ActiveX support" and protect again. Your embedded DLLs will be correctly registered from the protected application. Notice that your application must be running with admin's rights the first time that is executed, so the registration of the bundled DLLs can be performed. You can add an admin manifest from the Extra Options panel.
