Trying to install JRiver v220108 on a Windows v1703/15063.296 results rapidly flashing installation window which loops indefinitely and thus installation fails. This is due to a software conflict with Stardock Windowblinds v10.62. Problem has propably something to do with some UI element.
Using JRiver Mediacenter while Windowblinds is installed causes JRiver Mediacenter UI to freeze (creating dialog boxes fails). Problem does not exists if Windowblinds is uninstalled.
I hope Stardock development investigates this further, as it's it is impossible to use JRiver Mediacenter while Windowblinds is installed.
