hi all! Now im running W2K8 R2 Server on an Dell machine. Works very fine! While trying to install RT7 Server Customizer (all latest versions, x86 and 64) on W2K8R2 Server 64 bit, the installation stops with an error: "you need at least framework 3.5 for installation"... My server runs dotnet framework 4.0 and the error is still there. I cant install Framework 3.5, the following error occurs: "Windows Installer is not working, try to reboot..." reboot does NOT help in this case! Any hints for me in this case? Best regards Peter BTW: I modified the AIO "OOBE.cmd" script from W7 and entered the serials and "Edition-ID" for all vendors and editions. May I post the new script for anyone around here?
