I am not sure if any one encountered this before, Coveo pre-requisites on latest June 2016 version of CES failed on my local(this used to work fine before), The only change I realized this time was I am using Windows 10. I had .netframework 3.5 enabled already, but, Coveo installer was trying to install again causing fatal error. I could not move forward with installation.. Upon research I found the below issue on Coveo Q&A site. I followed it and it worked. It’s kind of not fair that I need to do regedit to make CES install fine.
I added my concern up on the below Coveo question and answers as well. Let’s see if Coveo does something for us not to have to edit the windows registry to make their product work.
More details on the link below –
Screenshot for reference on what i did to make this work.
Note – Make sure you create a system restore point and back up your original key before modification, just in case if it causes issues you can revert your changes
