Hi, I have APC 4100 that need to do offline installation to the Cfast Express card. After compilation is complete, i didnt see my cfast card as an option to download into. Just to test, I using Automation Studio 4.12 offline installation, and the card appear. ![image](https://europe1.discourse-cdn.com/brcommunity/original/2X/7/71a0fc637ba681ab9394b6f844ba4049cc3ea4ac.png) AS 6 transfer Setting, can see there is no option for CFast card ![image](https://europe1.discourse-cdn.com/brcommunity/original/2X/3/3b1c45e61d38e9887a36d9ca67ef7e531e3ccf6a.png) AS 4 transfer setting, can see the Cfast card ---

Hi, I’ve no idea right now what the reason could be, but 2 questions maybe helping us to identify the cause: - is the Windows service “B&R Disk Image **6** ” installed and running? ![image](https://europe1.discourse-cdn.com/brcommunity/optimized/2X/a/aa115ee452d64bdf4d05ec1efc60aaeb36111708_2_517x44.png) - Is the CFexpress card displayed in Windows Explorer as drive? (so is the card partitioned and formatted) Best regards! ---

Hi @alexander.hefner Yes the B&R disk image is running. There is no CFexpress card partitioned at the Windows explorer. This is a new CFexpress card from APC 4100. As expected, there is no partitioned created. Since AS 6 cannot detect my cfast card, i had to use Runtime Utility Centre to perform an Offline Installation. Or we could use Disk Management to create the partitioned first. But why AS 6 cannot detect if there is no partitioned created but AS 4 can detect? Is there is some security measurement implemented at AS 6? fyi, i tried with my customer PC, both our PC behave the same, we cannot do offline installation using AS 6 if there is no partitioned create yet for that card. ---

Hi @Mohd_Fauzul, to be honest I don’t know the internal differences between the the Disk Images Service (4) and 6, I just know that Automation Studio 6 uses the “B&R Disk Image 6”, while Automation Studio 4 uses “B&R Disk Image”. And it should be the same for Runtime Utility Center (PVI 4.12) and Runtime Utility Center (PVI 6) → like Automation Studio, also RUC uses the appropriate service belonging to the version numbers 4 or 6. I don’t know why there are differences and what’s the reason behind: it could be security related, performance optimizations, to stay compatible with new windows versions, or just anything else. Normally, B&R delivered storage cards (CF / CFast / CFexpress) preformatted in past, as I know. So maybe there was some mistake in delivery, or something has changed → I recommend to ask your local sales or support representative about that. Best regards!
