Problems running OOo on a Network

Hi there

I'm a Physics teacher who wants to use OOo on the school network but the Network manager refuses point blank to agree (despite it being the office program of choice of many of the pupils).

I use your excellent portable OOo from a Flash drive and it works fine on the network, so I tried to load it onto my allocated disc space on the network. This again worked fine, for a day, but now refuses to boot. The OOo flash screen comes up, a second or two passes and then you get a windows error message saying "The application cannot be started. An internal error occured" along with an OK clickable button. Click this and the application stops.

I'm pretty sure that the Network manager has knobbled it in some way, but have you any ideas as to why it won't work, and what I could do?

Incidentally, Portable Firefox works out of a folder on my Network space without any problem at all.

Will my bootstrap.ini help??

[Bootstrap]

Thanks for listening.
