I have a driver problem, the driver only works on 32 bit. I used XP mode but it isnt that good so I thought trying the same thing with virtual box in seamless mode. Now when i try to start a process wit this command:

C:\Program Files\Oracle\VirtualBox>vboxmanage guestcontrol test exec "C:\Windows\System32\SnippingTool.exe" --username Administrator

First he gave me the VERR_UNRESOLVED_ERROR but i fix that with changing the policy for accepting admin logins with no password but now i get this error:

VBoxManage.exe: error: Concurrent guest process limit is reached.

Someone knows how to fix this? (I'm using Windows 7 64 bit as host and Windows 7 32bit as guest)

Just make a password for your admin. Then give the password with the command (dont forget to get the right user) and it will work.
