As per title of discussion, if I start Indesign normally, the application window never appears. If I check Task Manager, I find there is an Indesign.exe process running for each time I have attempted to start the program. If I 'Kill' all these tasks and then use 'Start as Administrator' the software will run perfectly.
I am running the software with an account with Administrator priviledges. I have no problems with Photoshop or Illustrator (or any other software).
I have tried resetting the preferences
I suspect this is something to do with registry permissions, though I have no idea why they might be set incorrectly.
