Common APPLICATION Opening Problems

Microsoft .NET Framework Disappeared

If you attempt to load your APPLICATION file, you experience a message such as "Can't Open APPLICATION Files". Customarily, this means that Microsoft .NET Framework is not installed on %%os%%. The typical path of opening your APPLICATION with a double-click won't work because %%os%% cannot make the program connection.

Tip: If you have another software that you know opens APPLICATION files, you can select it by hitting the "Show Apps" button.

Wrong Version of Microsoft .NET Framework is Installed

Sometimes your installed version of Microsoft .NET Framework won't support your ClickOnce Deployment Manifest File file. If you do not have the proper version Microsoft .NET Framework (or any of the other programs listed above), you may need to try downloading a different version of it, or one of the other software applications listed above. This problem is predominately due to having a ClickOnce Deployment Manifest File file version that was created by a newer version of Microsoft .NET Framework than what you have installed on your PC.

Tip: If you right-click on your APPLICATION file, then select "Properties" (Windows) or "Get Info" (Mac), you can obtain hints about what version you need.

Summary: Not having the right Microsoft .NET Framework version on your computer can cause problems opening APPLICATION files.
