Rated 4 out of 5 stars

I thought I had a problem but Andy quickly , thanks, got in touch and I rethought the download ... turned out one of my security programs may have blocked it.

4 stars only because software is never finished!

Now installed and looks like it's well. Just what I wanted.

Problem for W7 64bit??

I have many users that are using the addon on WIndows 7 64 bit systems and i never got any issues from anyone.

Can you please try reinstalling it. I will check again thoroughly on Windows 7 64 bit and will get back to you! Thanks!
