Installing the Setup
The first necessary step is to download and install the new developer setup. There are two different ways to download your copy of the new full version setup.

If you are an assigned developer, you should have received an e-mail with a download link that is valid to download the full version three times.
If you did not receive an email, please contact the account owner or our support team for assistance.
Once you have downloaded the new full version setup, run the setup and follow the instructions to patch your installed version with the latest service pack files.
Checking File Versions
You can check the file versions to make sure that you have the correct version installed. The file version of all assemblies have the same pattern. The following sample shows the file version of the core assembly TXTextControl.dll.
32.0.2500.500
| 31 | Major | This number defines the main product version number. |
| 0 | Minor | The minor product version number (very rare in case of TX Text Control). |
| 2500 | Sequential/Patch | This number is a sequential number of this assembly. The last digit defines the patch version (service pack version). |
| 500 | Status | 500 defines that this is an official release version. |
