DLL error message in app

Have a user running my app and he get the following error:

The Windows app folder from the Xojo build has the dll in the folder with the .exe.

I know very little about windows, any suggestion?

Guessing a bit here. It seems a common problem according to a search. Possibly there is more than one version of the .dll on the PC but the incorrect one is registered. Some ideas here:

Else, redownload and install the Microsoft Visual C++ runtime.

I suppose you made sure to have your installer place all the DLL that come in Extras/Windows Runtime/Files/x86 or Extras/Windows Runtime/Files/x64 depending on the version of Windows ?

Thanks Peter and Michel.

Have passed the info to my user.

Have made change to the Inno process as recommended by Xojo.
