Thanks Friedrich,

I don't understand your reference to fonts, that's not something that concerns me at the moment. Also I would never install files in a loop, that just seems to be asking for problems.

Yes, I know I can redesign the install so the dlls get compressed and installed only once but I couldn't tell from the documentation if this was done automatically or not. It made more sense to ask first before I did the work of changing the install. With your information, I now know what I have to do.

Thanks again.
