Whenever I try to run NWN Tileset duplicator, I get an error saying:
"Run-time error 429
ActiveX component can't create object"
Likely due to you having an updated version of windows with increased security built in.
Windows 8.1 definitely has issues with this.
I was forced to REINSTALL the tileset duplicator, but to do so was a bit of a pain. I had to extract the original .rar file to D:\Temp or C:\TEMP with nothing else located in that folder. Then I had to set the setup.exe file to run in winxpsp3 compatibility mode ( I set default for ALL users just to be safe). I then ran the install, and did NOT allow it to overwrite the dll files for windows I think the error message was something along the lines of a warning about keeping the file or using the new file, I kept the orginal windows file instead of allowing this ancient setup.exe to overwrite with outdated crap.
I did try to run the setup from any sub folder deeper than \temp and I would get errors and the setup could not find regsvr32, OR could not find the .cab file and a few other errors as well.
Anyway, once I reinstalled it from the d:\temp folder, it seems to work. Again, your priviledges have to be high enough to allow the program to run. I have already set my neverwinternights folder to give my user name FULL privs, because soo many of the nwn utils were not written to work inside of a restricted environment, and by setting the privs that way, I could get things working. Be absolutely positive to work on a COPY of whatever original tileset you are attempting to duplicate as the duplicator needs to overwrite files during it's process and can cause damage to original files when it does things.
Windows 8.x is a real pain in the arse.
