I have Indsign CC 9.2.1 32 bit running on Windows 7. As of last week we are not able to choose a different printer from the drop down menu. It is set to Postscript File and we get an error that reads "Printer selection failed restoring to previous selection" when we try to change it. This has been working for several years with no problems. We have made no changes to the network. We thought maybe it was a windows update so we went back to a restore point from before last week. This work on most of the 7 computers. But I have two that just won't work. I would be grateful for any help.
Here is what I found to be true in my case. We have Viper antivirus and it was causing the printers not to change. I had to put in an exclusion for the InDesign program folder and because we are on Windows 7 also the ProgramData folder. This solved our problem.
