Issues with update 28.0.226 to 28.1

SOLVED

Having issues updating client manager.  All users (remote access) are set up as administrators, but all machines cant get passed theV28 data access components section.  Getting codes 1603 and 1921 and also one that says another installation is running - please would someone help us get passed this.  Have tried updating with software both open and closed. On different machines. Have even tried to do a fresh install. 

 

Thanks in advance!
