Hey admins/cnc net creators,
Just a heads up, I run my RA2 in an XP VM and when my client began updating, I was getting the error shown in the attached image.
After 3 hours and a fresh Origin reinstall of RA2, I still was getting the same issue. I found out that it was Avast's "File System Shield" that was causing the problem of the .dll not being able to update (I've got Avast Free Antivirus 2015 installed). Disabled it and it updated fine.
