I do hope you mean the Poser 7 Runtime, because V4 (and 4.1 and 4.2) don't work, or at least aren't supposed to work, in anything prior to Poser 5, and she's got big problems there when it comes to loading.

Nope I mean Poser 4.  I didn't get poser 7 until recently. V4.0 and  V4.1 loaded fine, but I had problems rendering...sometimes.

As for uninstalling V4 and V4.1, when you install V4.2 the installer will take care of all that.

Actually it won't, as I said V4.0 and V4.1 are in the Poser4 runtime and I want to install V4.2 in the poser7 runtime.

Remember my question; *Do I still erase V4.0 and V4.1 in the Poser4 runtime if I want to install V4.2 in the Poser7 Runtime?
**
*I also purchased things like expressions, etc for 4.0, V4.1, will they still work? do I have to uninstall them from Poser4 and install in them Poser7 or can I load them from the Poser4 runtime?
