DASYLAB 2016 Missing Control Switch Module

[Labrat]

Today (4) of our Dasylab 2016 installs began erroring out with the Control Switch Module in our worksheets not working. Switch shows up light grey in the Control Modules list but not able to use..?

DASYLab LITE does not include switches or buttons. All the other versions do. Run the Configurator utility and check the Version field (in the Included Options section) to determine which one you have.

We have the Basic and Full versions and all worked fine for years up until yesterday, it appears our security software 'Bitdefender' decided to remove the 'contr1.dll' file.

3 of 4 PCs are working now, still having issues with 1 PC.

Hub 0 & Hub 1 are missing, thinking might be another dll that was removed?

That's strange; I have Bitdefender and DASYLab on my computer and have yet to experience the problem. A simple reinstall should fix it.

Tried uninstall/reinstall and same issue. 

The Modules under Files: Backup Data, ODBC Output, and ODBC Input are all missing (there but greyed out)?

Is there a .dll file that contains these I can verify is missing or not?

UPDATE:

For unknown reasons, after installing DASYLab 2022, our security software Bitdefender removed contr1.dll from the DASYLab folder.

Once we replaced contr1.dll all of the Control modules are now present and functional.
