--- Comment #2 from Susan Cragin susancragin@earthlink.net 2013-12-03 08:33:44 CST --- Hello, Leo the bugreporter. NatSpeak 12 and later does not run well in Windows-XP. This is a Nuance "bug." Users have reported that a critical file is missing. Nuance has posted instructions saying to download a certain Windows DLL, but here's what I think.
Try first running winecfg on your existing wineprefix and update the version to Windows 8. If that doesn't work, you may have to re-install on a new wineprefix that has already been set to Windows 8. BEFORE YOU DO THIS be sure and remove your existing NatSpeak installation using wine uninstaller. That way, you won't use up a license.
This should work. Please report the results to this bug.
Note to self -- installation instructions for 11.0, 11.5, are severely obsolete. And 12.0 and 12.5 should be updated.
