Problem loading old Add-in in Inventor 2011/Windows7

[tclayton]

Recently we upgraded our systems to Inventor 2011 on Windows 7, from 2010 on XP Pro. (Obviously the add-in ran fine there). I also downloaded and installed VB 2010 Express and migrated the add-in project. I rebuilt the solution on VB2010 (running AS Administrator) and got no errors. The Add-in shows in the regisrty, but does not appear in the add-in manager. I did not run the .bat file to register the add-in, I just let VB do it when it built the solution.

Is there something about the new system I dont know?

Are you working on a 64bit machine?

[tclayton]

Yes, I forgot to mention that earlier, the previous (XP) machine and the new one are both 64-bit

VB6 Addins won't run on 64 bit machines.  They need to be rewritten in .Net

These were originally written on VB 2008 Express, then migrated to VB 2010 Express.  Like I said, they ran on a 64-bit machine before.

Additionally I've tried registering the Addin using the .bat file.  Error message below

RegAsm |: error RA0000 : Failed to load 'C:\VB2010 Projects\Projects\EventMonitor\EventMonitor\bin\EventMonitor.dll' because it is not a valid .NET assembly

Press any key to continue...

I think I've solved the issue, VB Express 2010 apparently works in a .NET Framework that either Windows 7 or Inventor 2011 doesn't care for.

I uninstalled VB 2010, deleted the migrated project files and registered the older ones built in VB 2008 Express. They run

I had the same issue migrating to Express2010 and found out its because 2010 uses framework 4

here is what i did to register my old 2008 dll's after migrating them to 2010.

@echo off
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\RegAsm.exe /codebase "C:\MyAddins\MyAddins.dll"
Pause

This works fine for all my migratet Express 2008 projects.

Only disadvantage is that if you migrate to 2010 you need to install framework 4 on all machines where you want to install your addins? and all win Xp computer must be upgrated to sp3?

Hope this helps you.
