AVG won't install error code 0xC0070643

[NzxtAidan]

My AVG wasn't installing updates so I uninstalled it and try to reinstall it but it failed and came up with 

"Description: General error (0x0643) Error code: 0xC0070643"

I've googled it and ever solution hasn't worked, anyone else who had this problem had third party anti-virus programs installed and disabled it and it fixed it. So I tried installing any anti virus/ malware  which was only malwareabytes but this achieved nothing and the same error code came up. I've tried lots of other things such as trying installing on other hard drives and SSD's and different versions of avg and turning my computer on and off again but none of these seem to work. I tried to contact and I got a hold of customer service but they told me only people who pay for avg can get help for them and I had to use the forum which was useless so I've decided to try to use the best forum I know.

 

If you can help me please reply,
