If your PTF installation did not complete correctly then it is most likely that you do not have the correct tables installed. I suspect that the Workstation install on the new Accounting computer was incorrect and that would result in the type of error you are receiving.
You need to verify that Adagio G/L is in fact being executed from L:\Softrak\ALWin and if that is the case then the files in that directory must NOT be marked Read Only. You should then try to get an install that does not give you any error messages. Have a look at the INSTALL.LOG and INSTALL.TXT files in the ...\Softrak\ALwin directory using Notepad. These file might give some indication of what is going wrong.
You most likely will need to contact your dealer who helped you set up Adagio.
