This has taken about 4hrs to download and install and been stuck at 90% for about 30mins now, is this normal?

Hey there @MRayzee! Welcome to the community! Sometimes the installation can stall for a number of reasons. The most common is harddrive write speeds, windows user access control asking for your permission in the background waiting, or close to full storage install location. In most cases it shouldn’t take too much longer. If it stalls and fails you may need to turn on install logs in the launcher then trying again.
Hello and thanks for the prompt reply.
Sorry i posted in the wrong section 
Its at 92% now, I will just have to wait, I wish I didnt unistall it a while back

No worries! After it finishes, test it out and let me know if you have any issues launching. If it’s all good when you’re done, make a final comment clearing this issue and mark it as the solution.
