Problem
CAT requires both version 3.5 and 4.5 (or later) of the .NET framework. If the correct versions of .NET are not installed on your PC, then you may see one of the following issues:
- CAT fails to start and gets stuck at 10%
- Report generation does not work or generated reports contain no images
Solution
- Verify the versions of .NET that you have installed on your PC. Both version 3.5 and version 4.5 (or later) must be installed.
- The full version of .NET 4.5 (or later) must be installed. Note that the Client profile and Extension packages are not the full framework. If, in your Programs list, you see something similar to below, then this is NOT the full .NET version and is insufficient to run the CAT:
.NET Framework 4 Client profile 4.0.30320
.NET Framework 4 Extension 4.0.30320
- In some cases, version 3.5 needs to be enabled. This may not be the default for a Windows installation.
You can check the installed versions using Control Panel→Programs and Features (or the equivalent):
To check if .NET Framework 3.5 is enabled use the Turn Windows Features on or off selection in this window.
