EMPLOYEEI’m confident0Hi Laura Wilkes:
Are you using anti-virus from Norton or Symantec?
Then the solution to this Norton/Symatec bug is to disable them while installing Lightning 1.5.0 as per:
QUOTE from https://getsatisfaction.com/mozilla_m...
I am also using Norton 360. I temporarily disabled the firewall to allow calbasecomps.dll to run. This will allow lightning 1.5.1 to install properly
EMPLOYEEI’m confident0Hi All:
Lightning 1.5.2 is available for download:
Lightning 1.5.2 is not yet approved (but you can download it from the link above and test it now; it's a pretty minor change so 1.5.2 shouldn't cause any problems) but when it does get approved in a day or two, it should fix the invite attendees bug.
