Win7 64bit + "XP Mode", Free WinStep Nexus 10.6.

I installed an app in the XP virtual machine (using "XP Mode"), this app created its usual start menu link in the XP vm.
Win 7 "XP Mode" automatically created a link in the Win7 start menu so that I can start the app inside XP directly from Win7.

This link has special command line, all on one line in "Destination" (I'm translating to English, I hope this is the correct translation of the symlink property field):

%SystemRoot%\system32\rundll32.exe %SystemRoot%\system32\VMCPropertyHandler.dll,LaunchVMSal "Windows XP Mode" "||1757eb75#1" "i4"

This symlink is working.

If I drag this link in the nexus dock it won't start, with this error (again translated into English):
==
Error while starting/running
%SystemRoot%\system32\VMCPropertyHandler.dll
Cannot find the specified module
==


The nexus properties show:
- File name: C:\Windows\System32\rundll32.exe
- Arguments: %SystemRoot%\system32\VMCPropertyHandler.dll,LaunchVMSal "Windows XP Mode" "||1757eb75#1" "i4"

I tried playing with these (ie: putting them all one line, quoting, ...) to no avail.

Is anyone using an "XP Mode" symlink on the dock succesfully?

Thanks
