Issues after installing the service pack 11.7.19


I have installed the service pack 11.7.19 and after the installation when opening the developer studio, following error messages are displaying.

Previous version : - 11.7.3
service pack :- 11.7.19

I just downloaded the service pack setup from the ESD site and ran the exe file.
  1. You did download the same bit version? (I would expect installer to fail, but you never know)
  2. Your windows folder should contain logs of your update - oesetup11719.log and oesetup11719log.1 - do these show any errors?
  3. Do you get the error before or after choosing a workspace?
  4. Do you get the error when choosing a new workspace?
  5. Do you have a .log file in your <workspace>/.metadata folder?
