Testing Silverlight on UFT One 2022 or 2023
Question ID: 110612

We would like to upgrade our UFT One machines to version 2022 or 2023 but we see that Silverlight Add-in is no longer available. We have Silverlight in our application. Is there some way to continue testing this with the newer versions of UFT One?

“UFT One 2022 and later: Following the discontinuance of the Silverlight development framework, UFT One no longer supports the Silverlight Add-in out of the box.”

Yes, this involves altering the registry, so please be sure to have a backup.
To enable Silverlight in UFT One versions post 2021 R1:

To enable the Silverlight add-in please follow the following steps to enable the add-in:

1. Make sure UFT is completely closed.
2. Open Registry Editor
3. Navigate to Computer/HKEY_CURRENT_USER/Software/Mercury Interactive/QuickTest Professional/MicTest/SettingInfo/AddIn Manager/WPF
4. Create a new DWORD
5. Name it EnableSilverlightAddin with Value = 1
