Have just tried the latest Beta 7.2.1494 on Win 10 Pro - https://vi-control.net/community/threads/vep7-whats-new-and-improved-v7-2-1481-2023-01-19-vst3-hosting.81869/page-7#post-5280775 . I think some progress, but still some problems.
The following VST3 plugins all failed the scan:
iZotope
Tonal Balance Control 2
Neutron 3 eq/compressor
Breaktweaker
Ozone 9 eq
RX6 de-esser
RX7 monitor
RX8 voice de-noise
Korg
Polysix
VIR Harmonic
Bohemian Cello
Steinberg
Spectralayers
u-he
ZebraHZ
I'd been having problems with East West Opus (current version) on the previous build. While it scanned, it would crash sometimes on disable/enable or a project load, or if it did re-load it would be silent.
On this beta build it seems to disable/enable fine and the project loads fine if enabled. However if I load the project with Opus in a disabled state, it crashes VE Pro.
Thanks for your continued work on the problem.
