I share a computer with my sister-in-law. Recently, she experienced a problem with the scanner function, but not the printer. I had used it under my user profile the previous day with no problem. Their are 3 user profiles on this computer and 2 of them will not pull up the Dell All in One Center without this error message: Runtime Error! C:\Program Files\Dell Photo AIO Printer 922\dlbtaiox.exe. She is a tech support person and did uninstall and reinstall and even removed from the registry ,but it still would not fix the problem. Dell's solution was to reinstall the operating system which I was strongly against. I reinstalled the AIO printer on my user profile and it is working fine for me, but on her and her daughter's profile there is a red x on the quick launch icon. The printer will print fine on their profiles but will not allow you to access the scanning function.Also, the scanning button on the printer itself will not respond on their profiles. Any suggestions?
