95 release did not have duplicates in the plugins folder. After installation release 97, at the opening of the program was to show the warning. Perhaps the new version and duplicated one of its plugins.

Check failure! This is probably a bug:
Duplicate plugin ID specified; check all ID strings are unique
Condition: plugins_by_id.find(cr::ToLower(plugin->GetID())) == plugins_by_id.end()
File: html5.cpp
Line: 205
Function: void __thiscall Exporter::LoadPluginsAndBehaviors(void)
Build: release 97 (32-bit) checked
Component: HTML5 exporter
(Last Win32 error: 6)
Healing was simple. Removing all of the plugins folder. Re-installation of the program. At this stage the program was launched, there was no error. Repeat to add additional plug-ins. Errors are still there, working again as usual.
