Hi!

I have the exact same problem but this methods didn't fix. I Run a Windows 7 Laptop (preinstalled) and want to install the Windows 10 Tech Preview Build 10130 but it gives me that error after I try to install

Hi,

I have the same problem, did you end up finding a fix for this?

Thanks.

Hi,

No, It still didn't work ;-; ... even though I did all the steps suggested above

I Just gave up to be honest... I guess I'll have to wait until the official release of

Windows 10 on 29th of July (even though I want to test it out NOW) - Hopefully

that would work?

Good Luck on finding the fix... and If you do please let me know :)

Thanks :)

Making sure these services are all set to automatic fixed it for me.

1. BITS(Background Intelligent Transfer Service)
2. Windows Update Service
3. Cryptographic Service

I have the same problem this did not help to fix it at all

Hi,

Did you follow all the steps given in this discussion above? If yes what was the outcome of that?
