I migrated from Vista 64 Home Premium to W7 Pro & Office 2010. I've been putting it off for quite awhile--even after having the software (since early Oct). There were 2 gates I needed to get through: 1) sufficient time to do a clean install, since Win Home Preumium can't be upgraded to W7 Pro (only a "Custom" install); and 2) all my fears of the process given how well upgrades (not new installs) have gone in the past.
The 1st surprise was W7 itself, which imported all my settings for every application I've reinstalled (via Easy Transfer to an external drive).
The 2nd surprise was that reinstalling both L3 & L4 was painless! Reinstallation was completely painless! I couldn't believe it! I've never had this little trouble with reinstalling software. And even when I wanted help in avoiding a 9Gb download, I found Dave Hooton's 3 ways to reinstall & they were spot on. Even my 1st failure to launch found help in several MVP posts to others who were experiencing the same. I was able to "remember" in your posts how to turn on logging. And in reading the log, it became obvious what my only problem was: all my settings were for beta, a later version than the production version I had installed. Logos' own posts about beta software provided a direct link to the beta installer. Problem solved. And in Office 2010, when I wanted to reinstall Smart Tags, once again the Wiki & Forum led me to Logos' posts on how to do Smart Tags in 2010. Problem solved in short order.
Thank you, Logos, & thank you, MVPs for all your help--your posts & your efforts to share your knowledge in the WIKI... You made my reinstallation painless.
Thanks.
