[SolarEdge Optimizer - string power difference error]

When trying to model SolarEdge Optimizers I am presented with the following error message:

"Inverter #6: With high Powers, the power difference between different strings should not exceed 2000 W.

However the string design input does not have unbalanced strings - they are actually both the same size...

It appears that perhaps the error is coming from not having a second/third string configured against these inverters??

[User Load Data Import Changed? - v6.4]

Is it just me or has the user's needs load data import been changed/broken on the new 6.4/6.4.1 versions.

I cannot import data files in the same format I previously could - and all attempts to follow the help instructions have failed.

I get the following when I try to import csv data - 8760 rows plus headers, two columns - date and power in kW

[Installation directory must be on a local hard drive]

I am trying to install PVsyst 6 on a new computer - and I get "Installation directory must be on a local hard drive"

 

Screenshot

 

I am running Windows 8.1 x64 on a Core i5 with 14 GB RAM and 256 GB SSD (C: - Windows install) + 320 GB HDD (D: - data). I have had PVsyst installed previously on this computer on a previous Windows install.

Is this something to do with the SSD (which is new)? - Though I have PVsyst installed fine for ages on my Sony Ultrabook which is Win 8.1 with 128 GB SSD?
