Gautam,
I am having the same issues with both Photoshop and Illustrator.
The Adobe rep helped me install the older version of Photoshop but now having the same issue with Illustrator.
Reverting to the older version is only a temporary fix and does not really seem to be the very best answer, can you offer a better solution that allows the end user to have the latest software and do away with the useless "Welcome" screen?
Yankee has the very same issue I am having. Changing up the preferences file does nothing to help. Need to delete or rename the specific file related to the welcome screen, can you offer help?
Thanks in advance.
