Hi, Marc.
This is me again. 
I could manage to copy the whole sfx3466625.tmp file just next the installation was interrupted by the error before closing the installation window. That file has 3 folders: eclipse, repositories, workspace. The largest size discTool.zip file is in the folder repositories as you know. I guess it is possible to make installation by hand (manually) but I do not know how. Can you help me? What files I must copy and where to make the installation by hand?
Best regards
Kirill
