HI
Sorry for the delay in replying and thanks for your help once again. I have copied down your repo and placed it alongside the parallella-hw directory (mine was called parallella-hw-master but I renamed it).
When I open Tutorial004_SimpleALU, I get the same message as above about the device settings do not match. When I double click the system.xmp in PlanAhead, it again reports the license error (ignored) then reports it can't find axi4lite.... I point it at the correct directory in the edk_user_repository, then it goes away and thinks about it for a while then does exactly the same again and XPS just closes itself.
I noticed I also get this error reported twice before the device settings one (I get them with the original project too):
CRITICAL WARNING: [Edk 24-160] BXML file generation failed for source 'system'. Please see console for any errors/warnings that may be reported.
The last thing that appears before XPS closes after a long pause is the menu title changes to System Assembly View. If I close the License Manager window that pops up, then the XPS immediately goes Not Responding and then quits shortly after. If I leave the License Manager open then I see the System Assembly View title change then the window closes.
This problem is similar to what happened with PlanAhead prior to the DLL patch for Windows 8.1:

Thanks again for your help.
