"Parameter is not valid" when checking in topics to TFS

[DMilkes]

I have RoboHelp 10 integrated with TFS 2013/2015. I just switched to a Windows 10 laptop and I mapped my local folders to TFS slightly differently than before: opening the RH project through version control and creating each local folder. When I check out topics, it is properly reflected in Visual Studio Source Control Explorer, but when I check in a topic, I get this pop-up saying "Parameter is not valid," and the topic is still checked out. There is no title bar in the pop-up so I can't be sure what application is throwing it. I have to check the topic in with Source Control Explorer and then check it in with RoboHelp.

What is happening?

That's a nasty one. What is your display scaling setting? Most laptops put scaling to 125% by default. but RoboHelp + TFS really don't like that. Try setting scaling back to 100% and see if that helps.

In case you are scratching your head wondering about that scaling thing. Here's something that may help.

Thank you Willian! It solved my  integration problems between PowerBuilder x TFS.
