I created a new user account under Win7. The only issue in my install was that the window that comes up at the beginning to report that Logos was downloading didn't close after the program had downloaded and installed. I closed it manually, having to click past lots of warning about the program not being installed, but I knew it was because it was preparing to download.
I let it download overnight and then stopped the download in the morning and scanned my resource folder from my SR-7 install and that finished getting everything.
Indexing took perhaps 2.5 -3 hours. It felt faster than when I first installed Logos 4, but I didn't keep a really close watch on the time for either indexing.
Datasheet is awesome! I would request the ability to copy and paste the table into a word processor/OneNote.
