VERR_CFGM_NODE_EXISTS

[RB]

I am running 4.3.0 on Windows 7 64bit, I already have one 32bit Win7 image running on it without any issues and I imported another 32bit Win 7 image but when I start this VM it gives me the below error :

Failed to open a session for the virtual machine <VM_Name >

A new node couldn't be inserted because one with the same name exists (VERR_CFGM_NODE_EXISTS) ..
Details :

Result Code:
E_FAIL (0x80004005)
Component:
Console
Interface:
IConsole {db7ab4ca-2a3f-4183-9243-c1208da92392}


I have installed the extension pack also + did restart the machine but nothing is helping, can someone please help

Regards

The configuration of the imported VM is not correct. Where is the image from and in which format?
