We wnaetd to downlaod theap installables on this m/c

So we tried to install sap donwlaod manager.

But it crashes and gives following error in the event application logs

Faulting application sap_download_mgr.exe, version 5.0.0.0, faulting module sap_download_mgr.exe, version 5.0.0.0, fault address 0x00021cb0.
