I got my hands on a win 7 computer (64-bit) and I have the same problem. I tried to google it and there were some answers about copying the MSVCR71.dll file to the same folder as the installer or copy it to the win system(32?) folder. It didn't solve the problem for me though.
When I uninstalled both the 32 and 64 bit versions of java on this computer, cultris will then install an older version of java (32-bit), but I still have the same problem.
I will try again another day. :)
