Additional SAP System on a maschine

Hi all,

we have a EP6 sandbox installation which is hardly used anymore, so i thought i could add a fresh NWCE System on the same maschine. Its a Windows 2003 Server btw. The EP6 and its database is installed on drive D (Max DB). Now when i try to run the NWCE installer it suggests me drive D as the installation drive and does not give me the ability to change that. When i continue the installation it does also try to install the new database(instance) into the already existing database, which is also drive D.

Now my question. Isnt it possible to add a new SAP system on different drives? I would like to add the new NWCE system on e.g. E.

regards,

Markus
