Excel error
Error communicating with Application. Please try again.
Invoke of: Open
Source: Microsoft Excel
Description: Microsoft Excel cannot access the file '...'. There are several possible reasons:
• The file name or path does not exist.
• The file is being used by another program.
• The workbook you are trying to save has the same name as a currently open workbook.
You may encounter a problem when trying to save Scheduler settings with a message relating to "config.xml cannot be found". The most common cause for this is that the config.xml file is saved in a write-protected location, for example, in Program Files.
In order to fix this, you need to make sure that the config.xml file is in a non-protected location, or that Scheduler has administrative privileges. This is a limitation of Windows where non-administrative privileges application are not allowed to write to certain location such as Program files.
Note: By default config.xml is placed in local user account, and not in write-protected location.
