XF 2.1 Having trouble installing an addon


New member
I want to install Xenpota 2 to have a nice looking announcements page but I cant seem to install it in my addons page
When I go to install Xenporta 2 in my addons page it says:

Could not process 8wayRun.Com XenPorta 2 Portal v1.2.2b.zip: File does not appear to be a valid add-on archive as expected.

The installation page for XenPorta 2 just sends me to xenforos page for installing an addon which didnt work when I installed it manually

Thanks in advance
