RE: How to force Quickbooks to open to "pick a company file"
Run QuickBooks with the command line parameters: - QFM ""
(space - space QFM space "")
For example:
"C:\Program Files (x86)\Intuit\QuickBooks Enterprise Solutions 19.0\QBW32EnterpriseAccountant.exe" - QFM ""
If you run QuickBooks from a shortcut, you can edit the shortcut and add the parameters in the Target field.
Note this is a version if getting it to launch with a specific company file, but in that case replace "" with the full company file path and file name.
