So these warnings are popping up now in Poser 11 Pro. They don't seem to do much, I can still use the software, but I am wondering where they came from. Anyone happen to know the significance of these? I've even deleted the folder it refers to on the bottom right, and that had no effect on the errors.

Have you Googled Microsoft Errors? Looks like the Add-On isn't working. Do you have it turned on or activated?

Also, they reference an "E" drive. Is that your setup for your Poser install? If not, then someone on the SM Poser team forgot to change the drive letter from whatever drive was being used for testing/preparing for release.

I've seen similar issues happen before, though never with Poser, or any of my other 3D software.

^Poser drive is D, always has been. This error just popped up magically this week.

^^Not sure what add-on you would be referring to

Well, I don't know about any "addons" specifically, but when I've seen something that's looking on a drive I don't have, then I suspect the person(s) who did the coding was/were using a "temp" drive on "their" computer for testing, and forgot to change it to the C drive by default. Of course, when you install to the D drive, as you did, it should then look for everything on that drive. I can't imagine why it would look for something on the E drive, unless it was accidentally coded that way.

These are the 'add-ons' that load with Poser. It looks like it can't find them. This is where they are in my install.

Are there any other Poser versions installed on your computer? I have encountered similar bootup issues which were traceable to earlier Poser versions, especially when phantom drives appear as part of the error. Just don't remember how I corrected the problem.

interesting. i'll if i can figure this out, maybe if i find those files
