No, there were no installation problems. I use a self built state of the art computer and the complete installation was done in 18 minutes. When I look into what is on the computer, Windows Media Center is shown there as a program.
I am tempted to re do another clean install, but hate to go through all the polishing up and re instaling my software.
I have also tried to do a computer repair, but this is not easy to carry out as my W7 disc is an OEM version and there is no free support from MS
