Cube 6.1.1 installation failing

I am trying to reinstall cube after it stopped working recently after an update to the graphics card driver for the Quadro K2000, intel chipset update and a BIOS update on the dell system from revision 16 to 17 but I am having trouble as it is not installing all the components of the package. it is definitely not installing any of the voyager software but it may be omitting others that I am unaware of.

I have tried deactivating the antivirus software (which was previously the cause of cube not installing properly) Can anybody advise what I can check to try to get this to run or provide details of local support available in Australia.

Much money to buy new machines go.
Ha ha.
