Installation fails to register even when "Run as Administrator" during the registration step.

Is it possible to manually install or otherwise work around the issue?

Hello Louis,

If you install an add-in that you developed, look in adxregistrator.log. By default it is located in {user profile}\AppData\Local\Temp\<ProductName>\adxloader.log; the ProductName part reflects the ProductName field of AssemblyInfo.cs (AssemblyInfo.vb).

Actually I am just installing Add-In Express for Visual Studio 2017 to develop an Add-In. Not the developed Add-In.

Hello Louis,

Please follow the suggestions below:

- Close all Visual Studio instances and make sure there's no devenv.exe processes hanging in the Processes tab of the Task Manager window before you start the installer.

- Make sure you are an administrator on the PC.

- Set UAC to its default level.

- In Control Panel | System | Advanced | Performance | Settings | Data Execution Prevention, set the "... for essential Windows programs and services only" flag.

- Remove the following registry key, if it exists:
HKEY_CURRENT_USER\Software\Add-in Express\{product identifier} {version} {package}

- Run setup.exe by right clicking it and choosing ?Â?Ð?ìRun as administrator?Â?Ð?í in the context menu.

If the above steps did not help, please restart your machine and run the installer. If the error persists, turn your antivirus software off for a while, install the product, and then turn the antivirus on again.

If nothing helps, please capture a video (you can use Jing; it's free) and send it to the support email address; find it in {Add-in Express installation folder}\readme.txt; please make sure your email contains a link to this topic.
