MAXtoA for 2022 - doesn't let me update

Hi everyone,


I have this weird issue, where I need to update the Arnold version.

maxtoa.jpg

I download the file and when I am installing it, I get this error:

error.jpg

And if I go to my Control Panel, there is no MAXtoA 2022 there.


I already went to C:\ProgramData\Autodesk\ApplicationPlugins and there is no folder there.


Anything that I am missing

Just to start a new thread.

Reinstalled Max2022. C drive this time. Still the same issue. I try to install the latest Arnold version and tells me is already installed. I temporarily fixed the issue by copying the MAXtoA_2022 folder from my work computer to this computer. I have no idea why this doesn't work. Control Panel still tells me there is no MAXtoA 2022 installed.

Can you run this command?

reg query HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall /f MAXtoA /s

I wonder if it's the 2023 entries. I would rename these two keys (eg put "xxxx" in front of the existing name) and test the install again.

HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Products\137CA9A5E40A09E4D8626D49EEA76DF6

HKCR\Installer\Products\137CA9A5E40A09E4D8626D49EEA76DF6

Go to Control Panel > Programs and Features.

Is MAXtoA for 2022 listed? Try to uninstall..if it's already uninstalled or the uninstall won't work, you should be prompted to remove the MAXtoA entry. Then the new install should work.

Hi Stephen, no there is nothing there. Only have MAXtoA for 2021.

In that case, I would get a Process Monitor log and see what's happening. Almost always it's a registry entry that is blocking the new install.

To get a Process Monitor log:

  • Download Process Monitor and extract it to a folder https://technet.microsoft.com/en-us/sysinternals/processmonitor.aspx
  • Start Process Monitor
  • Start capturing events (CTRL+E or the magnifying glass icon)
  • Start the MAXtoA install
  • When you get the "later version already installed" message, go back to Process Monitor and stop capturing events
  • Save the Process Monitor log to a .PML file
  • Zip up the log and send it (or upload to a file sharing site like dropbox)
