I recently installed CiviCRM 4.6.2 in our multisite Drupal 7 environment, running on IIS 8. I have CiviCRM 4.3.2 running on a Drupal 6 base without any issues on the same server; my plan is to migrate the D6 install and most of the data (contacts, etc) to D7.
Installation and configuration of CiviCRM went fine, as did importing contacts. However, I'm currently stuck on an issue that appears to have something to do with AngularJS and Windows/IIS paths, though I can't say that for sure.
When I go to Mailings -> New Mailing, it hangs - all it says on the page is "Initializing..." In Chrome's console, I see this error:
TypeError: a.headers is not a function
at n (angular.js:9720)
at n.$get.n.$eval (angular.js:14466)
at n.$get.n.$digest (angular.js:14282)

at l (angular.js:9698)
at M (angular.js:9888)
at XMLHttpRequest.F.onload (angular.js:9829)
In Drupal's watchdog log, I get this error (identifying path info changed):
MESSAGE Warning: file_get_contents(E:\webroot\drupalroot\sites\all\modules\civicrm/ang/crmMailingAB/E:\webroot\drupalroot\sites\all\modules\civicrm/ang/crmMailingAB\EditCtrl/report.html): failed to open stream: Invalid argument in Civi\Angular\Manager->getPartials() (line 203 of E:\webroot\drupalroot\sites\all\modules\civicrm\Civi\Angular\Manager.php).
It definitely looks to me like AngularJS is getting confused by Windows paths, but I'm not 100% sure that that's what's going on, nor how to fix it if I'm right.
