Regasm.exe missing

[karthur1]

I have an older add-in that I am trying to install.  When I run the install file, it comes back with "Can't install the file: regasm.exe does not existing!".

Can someone tell me where I can get this file?

Thanks

For what version of Inventor?

[karthur1]

Inventor 2022

[Frederick_Law]

It's also in v4.0.30319 folder and inside Framework64.

Might need to install .Net 2 or 4.

[karthur1]

I will try copy/pasting the file from another workstation. 

I tried installing .NET 4.0 and it would not do it because a newer version of DOTNET was already installed.

[Frederick_Law]

It also depends on which version .Net the addin was written for.

I only found regasm in v2 and v4.

I do have Visual Studio 2022 community.

[karthur1]

Copy/Pasted the regasm.exe and the regasm.config file.  That got it installed and then it told me this.

Downloaded and installed, but still can't get the app to work.  I have it working on other workstations with the same inventor, but this one is giving me a fit.

Thanks

Maybe there is also another way to install the addin. If I remember correctly the Regasm.exe is used to register the addin. That is not needed anymore from Inventor 2010 and beyond. (Retire Registry-based Add-ins in Inventor 2022.)  If you have a "Registry-based Add-in" then please have a look at this post. It explains how you can convert it.

Installing registry-free add-ins is as simple as copying some files to the correct location. I hope you have a computer with the addin installed. You can find the location of the files you need in Inventor.

You just need to copy the files/directory you find to one of these locations:

• Your addin is for all Users, Version Independent
  • %ALLUSERSPROFILE%\Autodesk\Inventor Addins\
• Your addin is for all Users, Version Dependent
  • %ALLUSERSPROFILE%\Autodesk\Inventor 20xx\Addins\
• Your addin is user-specific, Version Dependent
  • %APPDATA%\Autodesk\Inventor 20xx\Addins\
• Your addin is user-specific, Version Independent
  • %APPDATA%\Autodesk\ApplicationPlugins

Just a side note: It sounds like this addon is not getting any updates. That will be a problem when you switch to Inventor 2025 (or later). The way addins are created in Inventor 2025 is fundamentally changed. That means that your addin will probably not load any more in Inventor 2025. You might want to start looking into ways to update the addin.

As @JelteDeJong already mentioned, I hope that all (Autodesk Inventor Add-in) users are aware of the fact that many/ possibly all of the (free) Inventor Add-ins found in the Add-in Store from Autodesk will need to be changed and updated to .Net8, because these will not load anymore in the 2025 software of Inventor and beyond.

Most free provided Add-ins are not updated, I am sure of.

Good luck for those who are using add-ins that will not be updated, withing their business.

I see here a big big issue for many companies, in special those who have outsourced and have nobody in the house with any knowledge about programming to help them out very quickly and ad hock, or those who have downloaded add-ins without any support.

Not that is really that much of an effort to upgrade them, you still need to know how and what to do.

It is a lot of work as from my side seen there are a lot of updates for my bunch of add-ins over the years.

Normally an update did not cost that much of time, but for the Inventor 2025 it is time-consuming.

Please feel free to contact us or @bradeneuropeArthur to guide you with the process.

I do have it working on a few computers.  Will copy those files and see how it goes.

Thanks

I was able to solve this by copying the files from a computer where it was working to the %appdata%\Autodesk\ApplicationPlugins folder on the second computer.

Arthur,

I now have a solution moving forward.  Rather than relying on the add-in, I patched together some iLogic code to do the task. I am using 2022 and was even able to get this to run on a short-cut key (that's pretty slick actually).

In Inventor 2023 and above, I can assign a shortcut key to the iLogic code so that makes it even easier.

Attached code if anyone is interested.
