Question:

I have Studio 5000 versions 30, 32, 33, 34, and 35 already installed on my laptop and I am trying to install version 36. However, when I try to launch the setup file for version 36, I receive an error message stating "Error 2721: Custom action UnregisterLmgrd.20F26330_2F76_4897_8B98_98E7D7BD76B8 not found in Binary table stream."

Do you have antivirus protection installed on your computer? Have you set it up with administrator privileges?

If you encounter issues with the installation, it may be helpful to download a fresh copy of the installer and attempt the process once more. It is possible that a crucial component is either missing or damaged, causing the issue.

Robertmee inquired: Have you installed any antivirus software on your laptop? Did you install it with administrator privileges? Despite attempting to install as an administrator, my laptop still lacks antivirus protection and the installation did not go smoothly.

JeremyM recommended downloading a fresh copy of the installer and attempting the installation process again to fix any missing or corrupted files. Despite trying this solution, the same error persisted. Interestingly, the same installer file worked perfectly on a colleague's laptop. Out of frustration, I uninstalled all versions of Studio 5000 and reinstalled them, but only versions 36.00.01 and 36.00.02 continued to present issues, while other versions installed smoothly.

Sounds like this may be an issue with your installation package, suggesting some files might be either missing or corrupted. It’s worth trying a fresh download and re-install of Studio 5000 version 36. If that doesn't work, consider running it in compatibility mode for a previous Windows version. Studio 5000 may not be fully compatible with Windows 11 yet which could be causing conflicts. Definitely keep your software and drivers up to date to avoid these conflicts as much as possible. Hope this helps!

Hey there. This sounds like quite a tricky situation. From what I understand, each version of Studio 5000 creates its own Windows Registry entries, which sometimes cause conflicts with newer versions. In your case, it seems the installer can't find a specific custom action, hence the error. I'd suggest first trying a registry clean up tool, but remember to backup your registry first to avoid any potential issues. If that doesn't work, you might consider uninstalling the previous versions and leaving only the necessary ones. Lastly, ensure that your Windows 11 is up-to-date, as running an outdated version might create compatibility issues with the software. I hope this helps.

It seems like the issue might be related to existing DLL (Dynamic Link Library) files becoming unregistered or corrupted. This could have happened during one of your previous Studio 5000 installations. You might want to consider running the installation as administrator or check if there are any Windows updates that need to be installed. Sometimes, repairing the program through the Control Panel's "Programs and Features" option may also solve the problem. But please remember to backup all your data before trying to repair or reinstall!
