I have recently bought a new PC (windows 7 64 bit). I have successfully installed a number of programs that have previously been on the old PC running XP, including Photoshop Elements 9. When trying to install Premiere Elements 9 however it loads ok until the Templates section and I get two error messages " Windows Installer Service could not be Accessed......" and "The installation process has encountered a an error whilst installing MXSML. I have successfully loaded other programs since trying to install Premiere
On further investigation I find I Premiere 9 has installed but on starting I get an error message "online services could not be initialized. The same applies to Photoshop Elements 9.
I would recommend you contact Adobe Tech Support about these kinds of unusual installation problems. It could be a conflict with another program and more than we can troubleshoot here on the forum.
