Thank you very much. But however it is the wrong image. Sorry, I did not know the content within the file and so sorry that you had to investigate several images. But now I studied it a little bit so that I am able to be more detailled.
The problem is concerning the image "Win 7 x64 Entwicklung". And even if the system in the dialog writes that the virtual disk is missing the image can be started!
I now checked the VMX file and there should be the disk file "Windows 7 x64 Ultimate.vmdk". In the content of "Windows 7 x64 Ultimate.vmwarevm" I can find "Windows 7 x64 Ultimate-s001.vmdk" and so on (002, 003 ...) but not "Windows 7 x64 Ultimate.vmdk". How can I fix this?
Attached you will find
#1 the screen of the dialog, where I cannot enlarge the disk and where the is written that the file is missing,
#2 a screen of the configuration file
#3 a screen of the content of "Windows 7 x64 Ultimate.vmwarevm"
Thank you again.
