When using install shield express - Foxpro Limited Edition - I'm experiencing two problems.

1. Every time I build a new install, I have to regenerate the GUID/Product ID. If I fail to do this, then it will refuse to install on a machine where the Foxpro app has lready been installed, it want me to uninstall first.

2. Some of my data files are marked as Never Overwrite and some are not. However, it seems that data files are never overwritten regardless, I have to get the end user to manually delete some files prior to installation.
