Question Windows 8.1 install problem

I am running W8 on a 64 bit Aspire which is brand new (about 6 weeks old actually). I have twice attempted to install 8.1 from the Store but n both occasions received this:
unable to install OxC1900101 - Ox30018
the various Microsoft/W8 forums are unable to supply an answer to this problem. Fingers crossed someone here will have an answer.

Join the ever lengthening queue of those waiting!! Your error code (last part) I have not noticed before when trying to find an answer.

I have an Aspire 64bit and installed 8.1 the other day. Part way through the install I had to go into the boot loader to tell it where to boot from, it has moved My Documents so no programs can find them and totally deleted Avast anti virus.

And those are just the bits I know about!

Default W8 update problems

has anyone in M/soft come up with an answer to the problems lots and lots of people are having upgrading to W8.1 ? What do the error codes OxC1900101 and Ox30018 mean?
Its my fourth attempt this morning and I am still getting the error codes.

I'm not sure what the codes mean but I had the same problem. Researching I found that people had varying degrees of success with any of the following :-

Disconnecting all external devices
Clean boot
Removing / disabling Network Adapter
Removing / disabling WiFi (especially if manufacturer is Asus)
Updating video card drivers

None of them cured the fault for me but then I remembered seeing reports of removing TuneUp Utilities 2013 or 2014. Because I had already updated one of my PC's with TuneUp 2014 to 8.1 I didn't expect this to affect the other PC also with TuneUp 2014 but uninstalling it finally allowed the 8.1 update.

I was lucky because the culprit could really be anything on your PC. As someone mentioned in a post :-

'I just called Microsoft support. The technical support person told me that this error is caused by 3rd party background. It is not Microsoft error.'

It might also help if you check to make sure your machine is compatible.
