Hello Uwe,
THANKS A LOT !
Link to "Create page file..." solved my problem too!
Made a second "windows controlled" page file (swap file" on an other SSD.
Reboot > and GeoConverter finished without problems!
Usage of RAM and swap file are massiv.
After 32 GB RAM was filled up to 99% both swap files grow up to 104 GB !!!
Result of the new scenery >>>> GREAT!
Have installed south west Germany overlapping switzerland DLC in the Bodensee area and i think DLC is much brighter and looks not so really against new scenery.
THANKS AGAIN FOR YOUR HELP!
Regards Ralf
