I thought I posted this yesterday but I don't see it so I am re-posting. I apologize if this is a dupe or if I'm doing something wrong.
In any case, I uninstalled 2011, leaving the Settings in place. When I installed 2012, it did not import my existing tags from 2011. I had to manually create new tags again which took a long time.
Also, when I open the Software Uninstaller, it does not consistently load my newly created tags. Most of the time it's okay. Every once ina a while, though, I must close jv16 and then re-open it in order to get the tags to load.
I also have an anomoly toport. My Microsoft Streets & Trips 2011 was working fine (had jut used it). However, after I installed jv16 2012 and ran the Registry Cleaner, Streets & Trips could no longer find addresses. I uninstalled Streets & Trips and reinstalled it. It seems to be working fine now even after running the Registry Cleaner again as a test. Hence, I say that it is an anomoly that may not be related to the Registry Cleaner in 2012.
