The only recent change is the AP upgrade.
Properties on Payables is S:/Softrak/APWIN/APWIN.exe (this is the same on another workstation).
(S:/is a mapped network drive and exists on all workstations as such)
I can use windows to browse to that directory (with no error).
No errors of any kind occur on other modules (A/R and G/L).
The error message on AP occurs just after the program accepts the date and user pw.
Payables works properly on other workstations.
Version of Payables is 8.1E (130131).
I uninstalled the payables module then reinstalled from S:/SOFTRAK/ALLWKST/allwkst.exe, but I still get the error.
Thanks.
