I’ve execute msi installer of ParaView 5.12.0 then this message was shown.

![message](https://discourse.paraview.org/uploads/default/original/2X/0/06064aec0b33c8f32c68824ddcc05b4dbcc31dcd.png)

It means “Other version products are already installed. Installation of this version is unable continue”.  
I confirmed that it happen on both of Windows 10 and Windows 11.

Certainly, 2 versions ParaView 5.11.1 and 5.10.1 are installed my PC.  
Multiple version installation was possible until 5.11.1.

I want to use multiple versions ParaView together.  
How to install multiple version includes 5.12.0?  
Should I use zip package? Is it only way?

regards,

I’m afraid that I don’t have a better solution than using zip package.

Maybe @mwestphal or @cory.quammen can have some inputs?

I confirm the behavior and I think it is problematic.

The exact error message says:

> Another version of this product is already installed, Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs on the Control Panel.

A quick search seems to show that is caused by an issue on our Wix Packaging system:

There is a number that we should increase somewhere but we do not.

@earth2001y Could you open an issue on our gitlab: [https://gitlab.kitware.com/paraview/paraview/-/issues](https://gitlab.kitware.com/paraview/paraview/-/issues) ?

I believe this also happens with the .exe installer. I believe I had to remove older versions of ParaView from my personal Windows laptop.

As expressed by Mathieu, although this is tolerable, it is problematic.

Thank you all.  
I use zip package as work around until solved.

I confirmed that merge request about this problem is in the issue ticket.  
Is it solved at next release?
