(Current Build: 9841) PC Settings - Preview Builds - Download Now - Failed to download new preview build, please try again later. 0x80246017

Question

Hey ,
I hope someone can help.. been trying to upgrade from 9841 to 9860 for the last few days.. and I cant seem to get the preview build download part to work..
Seems like "80246017 Flight Settings Failure Content Download Error: Download failed" is the main error (more logs below)
And it doesn't seem like(from other blog posts) there are any manual downloads (ISO, .EXE's) so I'm stuck.
I know I could possibly do a full "clean" re-install of 9841 and then upgrade to 9860 but I really want to find out why its not working..
Cheers

Hi,
I had this same issue and tried many things to fix it. I finally found a fix with a small registry edit.
Open command prompt under admin and follow these steps (which I found here: 
http://answers.microsoft.com/en-us/windows/forum/windows_tp-winipp/error-code-0x80246017-when-trying-to-download-new/b188df4f-8e7a-443a-b584-61c4d59407d8)
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost\Applicability" /v "BranchName" /d "fbl_release" /t REG_SZ
/f
reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost\Applicability" /v "ThresholdRiskLevel" /d "low" /t REG_SZ /f
reg delete "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost\Applicability" /v "ThresholdInternal" /f
reg delete "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost\Applicability" /v "ThresholdOptedIn" /f
After you have done that open regedit and navigate to Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost\Applicability
If there is a folder called "recovered from" delete it. Then open up Windows Update in PC settings and go to preview builds and click Check Now
This worked for me. Hopes it works for you to.
