I installed CC right now, with the "Exchange Panel" right away from the new Cloud installation tool,
but inside PS CC the Exchange Panel says:
"Update Now
The Adobe Exchange update is now available...
...Please launch the Creative Cloud app and click the Update button for Photoshop CC"
And I can't do an update because I installed right away...
Cloud app says - everything is updated.
I also tried to install the exchange panel from the website,
but it seems like this is not compatible with cc extension manager,
it says that it has no valid signature...
Please AdobeGuys fix it.
