Errors unstalling v7.2.1

[Ken.]

Getting ready to update to v8.0.4 and trying to uninstall v7.2.1.

When trying to uninstall v7.2.1 I'm getting the errors below, any advice?

Thanks... Ken.

Proceed with the uninstall. Then try to do the new install.
If it still fails attach the failed files that failed on here.

OK, thanks.
Be back soon.

Did the uninstall of v7.2.1 and that rendered the forum inop, with only this error page showing:

Call to undefined function GalleryMemberUnviewedItems()

Attached are the two files listed in the uninstall errors.

Thanks... Ken.

Updated files attached.

Thanks, fixed now... also had some code in admin.php that had to be removed. The v8.0.4 installed with no issues and no errors, seems to be working OK.

Thanks... Ken.
