Troubleshooting - Windows Desktop app

At startup, the message 'Starting MyOffice' displays but MyOffice fails to start.

The most likely explanation is that MyOffice is already running. If you leave MyOffice logged on for several days the program may stop responding. The solution is to end the process and start MyOffice again.

Do the following:

  1. Open Task Manager (Click Ctrl + Alt + Delete)
  2. In the Processes tab look for the MyOffice process. With Windows 7 it's called 'moclient.exe', Windows 8 and 10 it's called 'MyOffice.NET Client'
  3. Select the MyOffice process by clicking the name once and click the 'End process' button on windows 7 and the 'End task' button on Windows 8 and 10
  4. Re-start MyOffice

TIP: It is possible to leave MyOffice running for days and weeks but we recommend that you close it down every few days.

At startup, any of the following messages are displayed:
'Server Connection Terminated'
'The application has generated an exception that could not be handled'
'MyOffice is unable to locate the server on which your data is held'
'Connecting to MyOffice.NET' displays continuously

The most likely causes are as follows:

(1) Your Virus Checker is preventing access
(2) Your Firewall / Port Blocker is preventing access
(3) Your Router has stopped routing
(4) MyOffice doesn't have read/write access to the location used for the 'Offline' files

To resolve the problem, you need to identify the cause.

Start with the virus checker. Temporarily disable your Virus Checker, re-boot your PC and re-start MyOffice. If MyOffice starts it indicates that the virus checker is preventing access and you need to configure your virus checker to allow the connections listed below.

If MyOffice fails to start, move on to checking the Firewall / Port Blocker. Temporarily lower the firewall and re-start MyOffice. If MyOffice starts it indicates that the firewall is preventing access and you need to configure your firewall / port blocker to allow the connections listed below.

If MyOffice still fails to start, re-boot the Router.

If MyOffice still fails to start, right-click on the MyOffice icon and choose 'Run as administrator'.

If MyOffice still fails to start, check whether or not MyOffice can write data to 'Local App Data' on your PC. To do this run the configuration program (Start > Programs > MyOffice.NET > MyOffice.NET Client Configuration). In the 'Offline Files' tab click the 'Test Folder' button. The Results list that is returned should end with the text 'Folder tests passed'. Repeat the test for the 'Local Settings' tab. If the test fails then email the entire results text to together with a brief description of the problem.

If MyOffice still fails to start after performing all the above checks, email or call the Support Line.

MyOffice Internet Connections
