Hello Vladimir,
Long time no see. Hope everything is great your way!
I tried to install iOptDetector v1.1 this morning and I received the following error.
In tS761 I noticed the DLL, Help files, Icons, and Libraries.
I tired to Load the DLL into the Package Manager without success.
I also tried adding the DLL to the Init.js file without success.
Note: I have not installed previous versions to date.
