Win7 64bit guest - Problem with VirtualBox Guest Additions

[blue8712]

Dear all,

I migrated a Windows 7 64bit installation from a physical machine into VirtualBox. Host OS is Windows 10 64bit. The windows guest can be started, but the VirtualBox Guest Additions don't work. The Service "VirtualBox Guest Additions Service" is not startable. In the device manager I see problems with "VirtualBox Device", "VirtualBox Graphics Adapter" and with the Intel Network Adapter. The error message is "For this device there are not enough resources (Code 12). If you want to use this device you must deactivate another". In attachment you find the

. Thank you very much for your help!

Best regards, M.

I'm very sorry, I searched many times for a solution, did't find, but after my posting I found the forum topic "Network+ won't work in Windows 7 guest on Ubuntu (Code 12)", now it works.
