No, users will download the Ditto app and it will run in place. No installation is required. Users will need permission to download and execute programs, but they will not need permission to install programs in order to use Ditto. However, users may be prompted to install the Ditto dependency package. This consists of standard Windows components that are typically already present on many computers. To avoid being prompted to install the dependencies, ensure that your PC is fully up to date, and that it has the Visual C++ Redistributable and .NET Framework packages installed.
