Is anyone else using Apollo Maximus and If so will you please tell me how to install it for poser 5. Also wondering how to install it for Daz Studio.

I had no problems installing AM to poser 5 and then to 7 I cant help you on D/S

what I do (with most stuff), is to unzip it to a temp directory, then copy the resulting folders to their usual places in Runtime. There's so much stuff for him, that it can get overwhelming. I have Poser 5, and he works just fine there.

D|S will use the same Runtime that Poser does, so you don't have to do anything special for D|S.

For poser, copy the downloaded files Into a directory just above Psoer Runtime. On my computer it looks like this: C:Program FilesCurious LabsPoser 6.
Then unzip the files (Usually right-click on the zip file) and use "EXTRACT HERE" option.
Do not use "Extract to [folder name]". If you do, the dorectory structure will be off, and poser won't see Apollo.

Do the same for each of the zip files.  That's all you need to do. Next time you file up poser, Apollo will be in your figures, I think under Apollo2007 folder (something like that)

If you haven't already, you may want to learn about multiple runtimes for Poser or D|S
