Sage 100

MAS 90 install v4.4 malfunctioning after repeat power outages. Users launch the program, enter login and password, then as the MAS 90 Desktop is opening it immediately closes. No error messages are shown on screen. Tried uninstalling and reinstalling workstation setup -- did not help. Would like to avoid a complete software reinstall if possible since integrated with JobOps, ShipGear, custom program from DSD.... any ideas?

Have you checked to make sure there are no hung PVX tasks?

Standard or Advanced? Does it run from the server?

Yep, none are running.

Standard, from the server.

Are any other programs malfunctioning? Have you run wksetup again?

MAS seems to be the only program with issues. Wksetup had no impact.

Try renaming SY_Console.M4T and SY_Workstation.M4t. As I recall, they are recreated new and empty when Sage 100 is launched.

Good thought. I renamed and the new files were created, but the desktop still closed immediately with no error.

Does the same thing happen when you run it in mas90 mode on the server?

Have you tried rebooting the server to make sure no files are locked?

I have seen that problem, but it was not caused by damaged files but rather caused by the auto logoff feature in MAS. If the times on the workstation and server are different MAS thinks the timeout has expired and closes the desktop suddenly.

Found it -> the BroadcastShutdown flag in SY_System. An oldie but a goodie? http://www.s-consult.com/2013/05/21/sage-100-erp-v4-3-users-see-login-prompt-launcher-flashes-and-disappears-solved/ Thanks to everyone for your suggestions and support!

Yikes, @GregStiles - What a diving catch!!!!!
