I upgraded wincc v7.0 from SP2 upd6 to SP3 on three different PC every one with win7 32 bit and every time same problem.
Installation was prohibited because SP2 web server is installed. I deinstalled web server from windows control panel, but installation still told me that web server is installed.
Step by step I deinstalled every wincc component until no wincc V7.0 Sp2 software was installed, but same problem installation tell me that web server is stil installed.
Any one has experience about this?
