Ubuntu + virtualbox + chessbase 11

Did you install W7 32-bit, or 64-bit?
Did you run a sysupdate on the guest machine? It seems that either there is a pending update for the guest windows installer, or for some reason the scripting host is disabled (e.g. by some stupid security software).
On 32-bit systems you can re-enable windows scripting host by running on a windows shell
regsvr32 vbscript.dll
Reboot (although it's not strictly necessary) and try again.
I'm running Linux Ubuntu 3.10 on my laptop. I have installed Windows 7 by the help of Virtualbox. When I am trying to install chessbase 11, I get the error code: 2753.
Any ideas what to do?
