Steps To Reproduce:	These steps are "best guessed" from the bug report. I am not able to test. 1. Place a VST effect in a non-standard location. 2. Set the VST_PATH environmental variable to include the non-standard location. 3. Observe that Audacity does not find the plug-in.
Release Note:	VST / LADSPA plug-ins may not be found in non-standard locations even if the location is included in VST_PATH environmental variable. Workaround: Put the plug-in, or a copy of the plug-in into C:\\Program Files\\Audacity or, C:\\Program Files (x86)\\Audacity on 64-bit machines.

Description Steve Daulton 2021-03-28 18:03:26 UTC

Originally reported here: https://forum.audacityteam.org/viewtopic.php?f=46&t=95330&p=343313#p324550

According to the manual, Audacity should search all paths specified by the "VST_PATH" environment variable
https://manual.audacityteam.org/man/installing_effect_generator_and_analyzer_plug_ins_on_windows.html#vst_install
This does not happen.

The proposed fix is that at line 405 of VSTEffect.cpp

wxStringTokenizer tok(vstpath);

should be:

wxStringTokenizer tok(vstpath, ";");

I have no idea how to test this - even after extensive research with Professor Google.  This is way above my nerd-grade.

I have written on the Forum asking the person who posted the original issue to ask if they would be prepared to test it:
