Installation of Natural One Community Edition in Windows 7 Professional 64bit

Dear all,

I’m trying to install NaturalOne community edition on Windows 7 64 bit and I get this error:

“Some products installed in C:\NaturalONE83-CE have incomplete configurations (see tree). You must exit the
installer, uninstall the products, and reinstall them.”

After that the installer stops and no software is installed on my PC.

Can someone help me?

Thanks

Maurizio
