I'm having problems installing CE on my laptop. I run the 64bit version of Windows 7. Software installer runs through, and then pings up with an error message "Cannot run CE main process" just before it finishes.
I'm sorry for the inconvenience. Let me suggest that you uninstall the old version of CE (8.0.85) and then try installing beta version 8.1.7. If you have an antivirus program, I'd suggest turning it off during the install.
If the installation is still unsuccessful, log in and use our live chat service to get additional assistance. The chat agent will have an extensive list of items to check. If necessary, he/she will be able to connect to your computer (only with your permission, of course) and take a closer look at why the installer "cannot launch main CE process."
