The latest ISO is not good, both on CLDX4 and CLDC!!!
Downloaded them 4 times, (from different servers) but always the same, the installer won’t start. So I used an older version that worked. Then after fully upgraded 4 systems no more (–sync) on all 4 PC’s , there were better day’s on calculate 
thanks

OK thanks for nothing,
all 4 systems are back in bussines, 2 CLDX and 2 CLD there where much problems but… it’s ok now.
Also downloaded the new ISO, but not tested yet.
