Developers who test their application installers on their developments systems, and not on a separate test platform, may run into problems when uninstalling projects which may throw off the registration of the UniToolbox controls.

It is not exclusively a UniToolbox issue, but rather affects ActiveX components in general. One way to avoid the problem would be to mark the UniToolbox binaries as 'Shared' DLLs in the application installer's configuration. They would then not be uninstalled (and un-registered) when the application was uninstalled.

We also have an example batch file that can be used to quickly re-register the UniToolbox controls:
