Windows 7
After upgrade from 4 to 5 at the start of LibreOffice I received the error message as follows:
The program cannot be started.
The service manager is not available
(“InvalidRegistryExeption: …”)
Start setup application to repair the installation from CD, or the folder
containing the installation package
Repair, remove and reinstall: the same result.
I could solve the problem with deleting the %APPDATA%/LibreOffice/4 sub-folder.
After the remove the program started normally.
