Seems like you are running a 64bit system. That is why it goes to a program files (x86) folder. Miq is better. I think the files that are in the program files (x86)folder are left overs from your prior installations. Use revo unstaller
http://www.revouninstaller.com/revo_..._download.html and use the advanced option so that it will find and remove any left over folders and registry files. Then reinstall to your c:\jeyo folder. One thing, set the permissions on the jeyo folder to full control for users. If you don't want to install revo, then after doing the traditional uninstallation, go to the c:\jeyo, and the prgram files (x86) folder, and remove all file pertaining to jeyo, then reinstall. See if it still puts any files in the (x86) folder.
