running new OO3beta after install

Hey community,

i've just downloaded the new portableapps-version of OpenOffice and truied to install it on my office-pc.
Installing it was successful, but not executing it. It tried to copy some files to my C:-partition, but due to missing administrator-rights it couldn't do that and failed starting OpenOffice.

I expected this version to be a suite which runs on EVERY pc (running under windows), without doing transactions to the current pc it is running on ?! (if i use it from stick it runs on several pcs).

What do i have to do to make OpenOffice run ?!?! I#m a little confused.

thanks in advance
Stefan
