Retrieve Updates Automatically

For the first time, when you click the Load ATSXL button on the CFG Worksheet, ATSXL will prompt you to check if there is any bug fixes or updates available.


Let's use twsATSXL.xls as an example:

Please save and exit all Excel spreadsheets, then run the batch script, i.e. update-twsATSXL.bat for twsATSXL, under your ATSXL directory, by double click it or run it in a Command window. The batch script automatically creates a unique time stamped sub-directory (i.e. Backup-2013101309453012), copy all critical files along with your Excel spreadsheets into this directory, then start the automatic updater to do the check and update.

A log file, i.e. twsATSXL-check-update.log for twsATSXL, will be updated with a summary of this update activity and the name of the backup directory. If you do not want backup directory to be created, you can supply a parameter nobackup when you run this batch script in a Command window. For example:

D:\myATSXL>update-twsATSXL.bat nobackup

WARNING: It is not recommended to skip this backup step.

This backup provides a way that you can roll back to previous version in case something goes wrong. You also get a chance to keep your own Excel spreadsheets with multiple versions that could be very useful later some time. You can delete these backup directories when everything is confirmed OK.

You may run this check and update batch script at any time. ATSXL will remind you to run it once every three weeks to make sure you receive the most recent updates from website.

In addition to use the above mentioned ATSXL's automatic update feature, you can simply download the latest package from this page, which always includes the latest bug fixes and updates.

WARNING: Please backup all your files before you overwrite them with the updated version just in case something goes wrong. That's why we recommend you to use ATSXL's automatic update feature.
