when doing so, I always get the error-message 'specific path is empty'.
When starting the installer, it only offers the de-installation of PSE 11; never the INSTALLATION.
I've worked on the de-installation with special de-installer-programm, that normally kills everything.
I deleted all registry-entries concerning PSE. Problem is not resolved.
I think that there is a hidden location, where the first install puts some information, that forces the installer only to offer DE-INSTALLATION, but i can't find out, whre it is.
I also tried creating a new user-account with admin-rights. No result.
I hope somebody can help
