I wrote an add-in while my company was on SW2006 that saves a pdf file when a drawing is saved to a certain directory. Worked great. When we upgraded to 2007, we just did an upgrade to existing installations. The add-in still works great...as long as you had it installed with a sw2006 installation. I ended up having to uninstall SW completely and then reinstall 2007 as a fresh install. Since I did that, I can't load my add-in DLL. I get an error that says "Unable to initialize the Add-in Component" I've worked with my reseller's tech-support and they took it to Solidworks API support and I still haven't heard any conclusions to the issue. I was wondering if anyone else has experienced this or if anyone has a way to fix it. I've verified that I have write access to my "temp" directory in the system variables and I've verified that the VBA folders exist.
