|I started getting this message with Nero 18.104.22.168 on a Vista machine.: "This action cannot be completed because the other program is busy. Choose "Switch To" to activate the busy program and correct the problem."|
It was driving me batty and Googling it didn't provide any solutions. So stopping one step short of trying the ASPI fix (and/or uninstalling and reinstalling Nero) I started checking out changes that I had made in the last few days and undoing them one by one. It turns out that when I was tweaking my system last night I disabled (and turned off) NMIndexingService. When I set it back to automatic and turned it back on, my issue was immediately resolved.
Hope this helps. :)
