When I open up my Express Accounts Plus software, it tells me there is an update. I am running version 9.07 and I think 11.0 is available. When I try to install the new version, I get an error that says "An application file could not be written. Please close all other applications and run the installer again." I have tried this numerous time and I get the same error message. This also happens when I try to update other NCH software. Does anyone know what I need to do to get the updated software loaded?
