Have to install to c:\ ?

I'm having a hard time with installation of SQL 2005 on Windows Server 2000. I'm trying to put everything on d:\ but I think it is failing as a result. Is there anything I should know about this?

Thanks in advance. -GregAs a follow up on this, as soon as I installed everything to C:\ everything worked stellarly. In listening to the traffic here, it appears 98% of SSRS users are using a non-distributed configuration. While the product supports installing its components on different machines (ie, Database on one box, IIS on anohter box, SQL Srvr on partition A, SSRS Web bits on partition B etc), I am guessing this process will not be well-documented and supported until a subsequent release.
