@xOv3Rz - No idea. Never ever had to do it. I've got to think that when I download ANY VP it notes my ID and links that to the DL and then it is part of my Registration, and thence my Install. No problem. On the Splash Screen, which you cant see so far, my PC ID is already there. It'll be the same for others too. The fact you can't get to the Splash Screen implies your PC ID hasn't been found/recognized, and won't proceed.
Here's a novel thought, go to your accounts and see if your B411 has been Registered?
@xOv3Rz - To confirm: I uninstalled B411. Rebooted PC. Reinstalled B411. Clicked to open B411 and I got an invitation to Register and NO PC ID was required. However, in the "About Screen" there is my Machine ID, as I said this must be held by MAGIX, and used as security to guard against multiple copies floating about out there on numerous PCs.
Something you could try is like @Grazie mentions, but I would rephrase it more correctly : restarting your PC.
Rebooting your PC as @Grazie mentions is often misinterpreted as powering your PC off, then powering back on. In the windows menu it is called shut down. Shut down is not the same as a restart in the menu. A restart in modern windows clears a lot of stuff and does not preserve what is active in memory. A shut down preserves your active state and memory stuff to help you start up faster, however if there is an issue, the issue is saved and you do not want that, this is one of the reasons sometimes issues do not go away with mere power on and off.
To absolutely clear a memory issue: first restart your PC, after is powered on again, then power off, disconnect the power cord, wait a few minutes so your power supply and motherboard can drain the remaining energy. then plug in the power cord and start the PC again. You could reverse the above procedure. If you are on a laptop, in addition to the power cord, remove the battery as well.
Lastly, instead of re-installing windows, you may want to check the integrity of windows itself if there are issues, sometimes one of the windows core files can get corrupt: use windows system file check:
1. Type "Command Prompt" into Windows search or Cortana
2. right-click on the Command Prompt result that appears and choose "Run as administrator"
3. After the command prompt opens, type: net user administrator /active:yes
4. Double check to make sure the command is entered correctly and hit Enter on your keyboard.
5. After running this command, the prompt will respond with: command completed successfully
6. Go back to the Windows desktop , and press Ctrl+Alt+Delete and select “Switch User” to find the Administrator account, then select it.
7. Install and activate your software applications onto this profile.
If this works for your issue, you can then copy the desktop icon for the software. Once you do that, you can then log back into your normal account and paste the desktop icon there to launch it.
