# What if the application does not launch?

In order for TelegramFXCopier to run properly on your PC, it is essential to have the .NET Framework 4.8.1 installed.

For a list of compatible systems see [this link](https://learn.microsoft.com/en-us/dotnet/framework/get-started/system-requirements#compatible-operating-systems).

If you do not have it installed, the application will not open. To resolve this, please install the Runtime version of .NET Framework 4.8.1, which can be downloaded from [this link](https://dotnet.microsoft.com/en-us/download/dotnet-framework/net481).
