I have installed Zoom Browser EX v6.6.0 on my cousin's machine (Win7 Home Premium 64-bit) and then applied the 6.7.2.33 update. It's running perfectly. Can't recall exactly where I got the files, but I did it last September. If you're trying to install the software from the CD that came with the camera it's likely only usable with WinXP.
It's a Rebel camera that she uses, rather than a IXUS 130, but the software itself is what we're talking about here.
The 6.6.0 installer file is 57MB, and the 6.7.2.33 updater is another 36MB. I can make both files available to you for download, if you PM me your personal email address. Again, I know I did some research trying to find these files back in September but eventually I did.
Now we weren't able to get usable Win7 drivers to support her old model Rebel camera. But that problem was solved simply by removing the flash card from the camera and inserting it into the card reader of her new computer. Win7 has no problem reading SD cards, and Zoom Browser has no problem sucking in images from cards. The card does not have to be in the camera for Zoom Browser to be 100% functional... just put the card into a card reader.
Now, will this all work for you and your IXUS 130? Who knows, till you try it?
