Try step 5 first - if that does not work try the full sequence.
1) Try saving to the desktop - to preserve your template work
2) If that does not work the save as a regular file to preserve you template info
3) Then uninstall
4) locate the install EXE and rigt click on it and 'Run as Administrator'
5) After the install is finished. Right click on the program shortcut (icon) and choose 'Run as Administrator'. Yous should only have to do this once.
