Error when trying to reinstall AVG internet security

Hi Zoe,
I will help you with the issue,
you can try to install AVG using latest installation files,
please find whether you are using 32 bit or 64 bit windows and
then try to download the offline installation files of AVG internet security accordingly
using this link http://www.avg.com/us-en/download.prd-isc
Let us know if you face any issue
Thank you

Hello,
I'm really grateful that you answered my question.
I have tried to install AVG internet security from the link that you gave me, but it didn't work either.
I just get this error message: "No action was taken as a system reboot is required." 
I took a screenshot as you can see below, the message was in dutch but I translated it ofcourse. 
There's also a code in it and I already tried to look it up but I didn't find anything.
I checked and there is nothing left on my computer from AVG internet security, so it doesn't make any sense at all?! 
Do you know what I should do?

Hello, I'm having some trouble reinstalling my AVG internet security program. At first, my AVG program did really weird so I wanted to uninstall it. It didn't work on the usual way, so I had to install the AVG remover. Then it worked, my AVG program is off of my computer. So a minute ago, I tried to reinstall AVG internet security and it gives an error code: 0xE001F946 and message: Event exec_finished
can someone help me please? I don't know what to do…

Hello,
I will try to use the AVG remote support and I will let you know how it turns out.
