Having installed Veeam FastSCP onto my Windows 7 (64) Ultimate workstation I was getting frustrated with the error messages I was getting ' Retrieving the COM class factory for component with CLSID [5F1555F0-0DBB-47F6-B10B-0AB0E1C1D8CE} failed due to the following error: 800700c1', a quick found the answer for me. Looking into the fix I found I realised that it’s a tad long winded and bloated (no disrespect intended, as it is the fix). So I thought to myself, did I actually need all of that for the fix to work. The answer is no.

Having looked at what was required (running ' corflags 'C: Program Files (x86) Veeam Veeam Backup and FastSCP VeeamShell.exe' /32BIT+' to resolve the issue with FastSCP not working on any 64bit Windows OS resulted in the above error message when trying to copy files between Datastores) I decided to see what happens if I just took the corflags.exe file and ran that instead of having the entire SDK installed, the results were that the program now works. Short Approach Download the Corflags.exe program from, copy it to a folder of your choice (I used C: Temp) Launch an elevated command prompt and browse to c: temp.

Now run corflags 'C: Program Files (x86) Veeam Veeam Backup and FastSCP VeeamShell.exe' /32BIT+ Now launch FastSCP and you should be good to go 🙂 Long Approach For those wanting to do the entire process the following describes what you need to do. First of all download the 64bit Microsoft.NET Framework 2.0 SDK from Once downloaded run Setup.exe Click Next Click Accept and Next Untick the top two boxes, unless you actually want it installed. Accept the defaults and click on Install. Once the installation is complete launch an elevated command prompt and browse to C: Program Files Microsoft.NET SDK v2.0 64bit Bin Now run corflags 'C: Program Files (x86) Veeam Veeam Backup and FastSCP VeeamShell.exe' /32BIT+ Now run FastSCP and you should be good to go 🙂.
