I get the same thing in Windows 7 and 10.... your version 8 should be no different. Here is a screenshot of the first helper app (Universal Serial Bus) while the VirtualBox install window is behind it. You can see that it is asking to install his helper app. With that checkbox ticked (Always trust software from Oracle).... I think it will install the other two apps without prompting. But I think you should have seen this during the VirtualBox install. I tried uninstalling from Win 10, and it didn't come back to this prompt, so I am guessing that they were not removed when I uninstalled it.i have windows 8
There is no need to do a custom setup. Accept the defaults. If you don't get the prompt to install the extra apps ("helper" was my term, not theirs)... then forget about it. You either did, or you didn't, but if you don't see what I described to you then you may have missed your chance. If so, we either have to hope that we don't really need them, or that we can install them later when they are needed. I'm not an expert with VirtualBox.... so my assumption was that they will be needed by most people, and that's why the popups appeared to prompt to install them.this is the new version of virtualbox (copied from the link) VirtualBox-5.2.4-119785-Win.exe
right at the beginning before the boxes there is something called Custom setup where it says to mark icons to decide. there are support options there. it is difficult to know how to get them all.
installed again but still no support apps so i have uninstalled again.
when next i start installing i shall do printscreen so you can see the alternatives i have.
Accept ALL DEFAULTS. There is nothing you need to change.... except to tell it to install those 3 apps, if they come back. The default for those apps is to NOT install, so you needed to be careful through that step.the default is with the 3 it seems. here is the next problem. which to select?
continue later. it is now past 3 a.m. so must sleep.
Hmmm, this is an unexpected problem. Although you may not understand what is happening, I think I do understand what you're saying.... VirtualBox is not giving you choices for 64-bit almost certainly because your copy of Windows 8 is a 32-bit version. (I have little doubt that your computer is 64-bit, but many manufacturers, like HP, would put the 32-bit Windows on them because it was a little cheaper).step 5 done, if default means uncheck nothing then i have chosen default. no prompts for installing 3 help apps have appeared. now i shall continue to step 6. no 64 bit option is given.
step 23 result "This kernel requires an x86-64 CPU but only detected an i686 CPU. Unable to boot. Please choose a kernal appropriate for CPU." I have no idea what that says and no idea what i have done wrong and no idea what the solution is but i suppose it means i cannot do the next step.
What i wonder is why at step 9 there was no Ubuntu 64 bit or x86 option but only 32 bit although the iso file is x86. if the only option made available is Ubuntu 32 bit then surely the iso file should be x32 and not cx86? i hope you understand my totally unscientific English.
