Windows 10 here. I was getting the error, too, until I replaced the AcriveX Flash exe in the installer with a regular flash installer. It seems that perhaps the LDD installer doesn't receive a fail value during the install that way.

Hey all! I joined just to respond to this. What I did: Make sure you have Flash installed already Install 7-zip or winrar if you don't have it already Download the LDD installer from Lego Download the Flash installer from Adobe Extract the LDD installer file (i.e. setupldd-pc-4_3_11.exe) (Extract to "setupldd-pc-4_3_11\") Drag the Flash installer into the setupldd-pc-4_3_11 folder Navigate into the setupldd-pc-4_3_11 folder Copy the name of the included (was packaged with the LDD installer) flash installer, then rename it (I added "_0" to the file name) - Could probably just delete the file, really Rename the downloaded flash installer with the name you copied from the pre-packaged one Double click LDDSetup.exe When it asks to install Flash, click yes What I found was that the newly downloaded installer was used, and I was told I was either installing an old version of Flash or already had flash installed, and was given the option to download a newer installer from Adobe (maybe I downloaded an old installer?). I clicked through to download from Adobe, and the LDD installer continued as though the Flash installation was successful. The file associations seem to have worked as a result of this.
