Title pretty much says it all. I upgraded to Nik7 from the latest version of Nik6. After install, Nik7 palette failed to launch; it could be manually launched from the PS file menu. Annoying, and I hope a fix is quick.
Note: I think there was a conflict, as both the Nik6 and Nik7 palettes were in the PS file automate menu. I hid the Nik6, closed and reopened a file in PS (and waited a bit) and the Nik7 palette appeared. Odd behavior, but it sort of is working as expected.
