Warning envSetval: Can't set the value of variable 'pathPurposeList', in tool......

Hi,

I am getting a series of warnings upon initialisation of Virtuoso. All errors are in the CIW window. All of the same type as below:

""Warning envSetval: Can't set the value of variable 'pathPurposeList', in tool......""

I have tried using "virtuoso -nocdsinit &" and all warnings go away but this generates a series of other warnings when new schematics are created or opened. I have looked in the cdsinit and cdsenv files but nothing I can see (in my limited experience) as obviously wrong.

Wondered if anyone could spot something wrong.

All files and CIW output attached.
