Keep getting an "unable to load" error with Autocad 2016.

[David Pagan]

I followed all of the installation instructions, but still can't get the arx app to load.

I reverted to manually using the APPLOAD command, but it still gives me the "unable to load" error.

Trying to use the nXt_21_64 version.

Anyone else having the same trouble?

I'm pretty sure AutoCAD 2016 is version 20 not 21.  Changing that would likely solve your problem, but other things can produce this error as well.

I'll bring this one to the attention of the Render Plus guys-- they should be in tomorrow.

Thanks Roy.

Took your advice this morning and loaded the 20 version. Worked like a charm.

I guess I went astray after reading this in the FAQ:

1. Type _appload at the command line.
2. Navigate to the folder where nXt was installed. This is normally C:\Program Files\AccuRender nXt.
3. Select one of the following files depending on your platform:
   • AccuRender nXt.arx -OR- AccuRender nXt64.arx (AutoCAD 2007 – 2009)
   • AccuRender nXt_18_.arx -OR- AccuRender nXt_18_64.arx (AutoCAD 2010 – 2012)
   • AccuRender nXt_19_.arx -OR- AccuRender nXt_19_64.arx (AutoCAD 2013 – 2014)
   • AccuRender nXt_20_.arx -OR- AccuRender nXt_20_64.arx (AutoCAD 2015)
4. Press Load

Did not assume that the version 20 would include BOTH Autocad 2015 and 2016.

Did assume that the undocumented version 21 was Autocad 2016.

(Is 21 for 2017?)

Thanks again.

Yep.  Autodesk used to have three minor releases for every major one.  They broke this pattern in 2015 with only two.  Major releases require updates of arx apps, minor releases do not.  I'll make sure we have current documentation.
