@the_tdog :

It's never been a standalone thing.  Though, Gérald did once show an image in a thread with evidence that he was toying with the idea, because it had an OBJ import button, and I really wanted him to go in that direction, but several years have past and that did not happen.

Did you mean the native Poser plugin?

And, yes, VWD is a standalone EXE that one can open up and look around in, but without either bridging from within Poser, Daz Studio, or Carrara, it is just a useless empty shell.

So, with that out of the way, what exactly is your issue?

Exactly which version is not installing?

Exactly which version of which software is the bridge software not installing?

I am running VWD EXE version 1 (last iteration) with native Poser bridge in P9 and PP2014, version 1 (last iteration via Philemo bridge) in DS Pro 4.9 and Carrara Pro 8.5, and version 2 with DS native bridge in DS Pro 4.12 on Windows 7 PC.

What, if any, are the error pop-ups stating?

Maybe the 'host' software version you are trying to install the bridges to are unsupported.

Maybe the OS you are trying your installs with have UAC issues, or compatibility issues.

WIthout better details, it is hard to troubleshoot your issues...
