Problem
A script error can pop-up when loading work instructions when a production sequence is running.
Details
Tascus used an embedded web browser to display work instructions. Originally, this was based upon Internet Explorer, which has since become unsupported.
This error message means that Tascus is using an older version of IE which does not support some functions. Tascus adds a registry entry to force it to use IE 11 to resolve this.
Recently it seems there has been a Windows update that overrides this registry entry, causing the script error to reoccur.
Solution
Update to the latest version of Tascus, which uses an Edge based browser (WebView2) this will ensure all features are supported and no error messages will be displayed.
Registry Entries
The Tascus installer will add a Windows registry entry in one of the following locations:
HKEY_LOCAL_MACHINE \ SOFTWARE \ WOW6432Node \Microsoft \ Internet Explorer \ Main \ FeatureControl \ FEATURE_BROWSER_EMULATION
OR
HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Internet Explorer \ Main \ FeatureControl \ FEATURE_BROWSER_EMULATION
This registry entry specifies which version of the Internet Explorer embedded browser (11) to use for work instructions.
If the registry entry is missing, this error message will be displayed on work instructions:
