Using WIndows 10, current with Windows Update
Windows 25, all updates installed
On my desktop, I can not use SmartMusic SoftSynth through VST - It does not show up in the Dropdown Box in the Score Manager. (Only my Garritan libraries show up)
If I load a file that uses SoftSynth, when I try to play it or go to the "VST Banks and Effects" window, I get a pop-up with the above error message, and the Score Manager shows "(missing)" instead of "SmartMusic SoftSynth"
I have no problems on my laptop, which is the same setup and operating system.
I have done the following:
"Rescan for VSt Plugins"
Verified that the softsynth_vst_x64.dll is in the "ProgramData\MakeMusic\Finale\VST Support" directory
That directory is not listed in my laptop's "Manage VST Plugin locations" and it works fine, but to be safe, I tried adding it to my Desktop's VST locations, but it did not fix the problem.
If I switch to "Play Finale through MIDI", everything plays through SoftSynth just fine, (MIDI Setup shows that SoftSynth is my default MIDI output"
