If the steps above do not help, try to convert the virtual machine using the Terminal commands:
There should be at least twice as much free space on your destination hard disk as the size of your source virtual machine. Make sure your Mac has enough hard disk space: Run chkdsk (checkdisk) utility in your Windows virtual machine (following the instructions from the KB115549) to fix possible hard disk issues and try to convert it again. Make sure your virtual machine is free of hard disk errors: Rename the virtual machine and try to convert it again. The VMware virtual machine file name may contain unsupported symbols, such as /, * or &. Try to split and then 'unsplit' the VMware Fusion virtual machine hard disk in your virtual machine settings before converting it to a Parallels Desktop virtual machine Make sure VMware Fusion the virtual machine is not encrypted. Instead I get the following error message: Error 41300: Failed to convert the virtual machine I cannot convert my VMware virtual machine.
