I now need to update my Advanced Installer installer to install on Windows 7, and I'm still using 7.1.3.
Should I upgrade to version 7.6.1?   
7.7 doesn't have a ".1" yet, and so I'm not sure if I should upgrade to the latest.
I'm looking at the enhancements and bug fixes, what does "Added support for both upgrade methods to Windows 7 Libraries" mean?   How will that help me in properly supporting Windows 7?
With 7.1.3, I had a few problems:
1) On Vista, my installer didn't have a Vista controls look and feel.  Is that fixed in a more current version of the Advanced Installer?
2) If the network connection was dropped while downloading a prerequisite from Microsoft's web site, the installer would hang.  Any chance that is fixed in a newer version of AI?
3) Within our installer, our background graphics would get slightly distorted, we would see two small vertical lines.  Any chance there might be a fix for that since 7.1.3?  7.1.3 fixed a few of the problems we had, but we have one remaining issue.
