Hi. I'm getting the same error message as oldie...I copy and paste with the added space, and it says a file name can't contain any of the following characters...I tried backward and forward slash. It won't allow it to be put in the box...help please...thanks!
Are you sure you added this in the Target Box with one space only? /msioptions "ESU_LOCK=2D40812E-974C-4EA2-8DCC-63C992D505B9"
Lisbeth, me myself had experienced the same thing, but thanks to vinzf's method I was able to install the .NET update successfully.
[QUOTE="pesho_georgie] Here is your fix.[/QUOTE] Thank you very much I will look at it later but thank you. .
Is this fix mentioned here supposed to be suited for the KB4556399 error? if it was I can't use since I am being told by the system I can't add any kind of slash special characters to the target line. Yes, there is just one empty space in between.
Failed the shortcut part at first. Tried it now anyway via the shortcut, started ok but it didn't work, installation failed in the end.
Windows 7, x64, Microsoft .NET Framework 4.8 Followed the instructions. I ran it as admin. I received this error message: Installation did not succeed Software update KB4552921 has not been installed because: Fatal error during installation UPDATE SUCCESS!!!! Thank you! I have no idea why, but I tried again (3rd try) and the update succeeded. I did NOT do a reboot between these 3 tries. Puzzling.

Hm, it worked now, which is great btw. Dunno how tho. Maybe cuz I have placed it inside the W7ESUItemp_10878 next to the W7ESUI.cmd? Anyway, it worked.
