Für die virtuelle Maschine 7_64_new konnte keine neue Sitzung eröffnet werden.

Cannot open host device 'COM1' for read/write access. Check the permissions of that device (VERR_ACCESS_DENIED).

Could it be that your serial port is already in use by some other app? Try connecting to it, e.g with putty to check whether it succeeds.

You can also find who owns the serial device via  process explorer +  WinObj tools.
First run winobj and see the device name for your COM1: select GLOBAL?? in the left pane and locate COM1 on the right. The "symlink" panel should display a device name, this would typically be \Device\Serial0.
Now run the process explorer and open the search dialog (<ctrl>+f), type the serial device name (e.g. \Device\Serial0) and press "Search".
As a result the file owner should be displayed.

Hi Misha,

thanks a lot for your help you are right, the problem was that the port was in use.... you can close this ticket.

Maybe you can add the result to the community forums cause I looked there before I wrote to you but I didn't found a solution. But I found out that more persons have this problem... In the User manual I didn't found a solution too.

kind regards Samuel

Thanks for the feedback. Not sure this needs to go to manual. The info will be kept here so others can search/find it.
