Error: Another instance of LibreOffice Portable is starting

I get the following message when trying to launch LibreOfficePortable.exe from my program:

“Another instance of LibreOffice Portable is starting. Please wait for it to start before launching it again”

I do need to execute several instances at once, and they do not conflict with each other, but this message pops up from time to time.
How can I avoid it?

What I have already tried according to some advice:

  • to delete App\AppInfo\Launch\LibreOfficePortable.ini (fails to start then)
  • to edit it and Data\settings\LibreOfficePortable.ini by adding line “SingleAppInstance=false” (nothing changed)
  • to delete Data\settings\PortableApps.comLauncherRuntimeData (doesn’t exist)

Thanks for any help in advance.

As I know Portable version do not run when there is another soffice running.

I think to do what you want is needed to have several installations in parallel.
