Windows 10: I Need Two Run Two Versions of Software. Windows Instaler Will not Let

I run HPTuners
Tuning and Diagnostics software for my vehicles.
They have since came out with a completely new platform V3.0xxx.
On one vehicle I have all set on V2.0.xxx and to migrate it to V3.0.xxx would be a disaster.

In Win7 its a matter of renaming the v2.0.xxx folder in Program Files(x86) to HPTuners_old. Then create a shortcut to activate the older version.
Then install V3.0.xxx as normal.

I have tried stopping the windows installer in services, renaming folder, but its no good. I keep getting "There is a newer version, uninstall it, yadda yadda.

Is there any help for this?

Can I run two versions of DirectX on my computer

Win 10 has four DirectX versions, 9/10/11/12 . MS only promotes the highest version the Windows version

in question is capable of using.

Windows does not decide which particular DX file of files a game uses. This is done by the game.

- You can find out which DirectX Feature levels your graphics processor is capable of using inDirectX diagnostics

( type dxdiag into the Run Command), under the Display tab.

- The first thing to do, particularly if you are using a clean installed Win10, is to update DirectX using

the DirectX Web Installer ...

Download DirectX End-User Runtime Web Installer from Official Microsoft Download Center

- There are several factors that determine if a game will run. If you list the name of the game or games in question,

and the brand and model graphics processor your machine uses, we will have a better idea of what

problems you may face.

The biggest issue on Win10 when trying to install or launch many
disk based games released earlier than '07 is

a 'feature' that MS has built into Win10 - DRM Blocking. I have more details on this in my post at

--- this thread ---

Other issue begin to arise with games released prior to '02.

You can use a program called "Sandboxie". It let's you create virtual environments, so called sandboxes. Within those sandboxes you can install a program independently from your real system. E. g. I use it for having two different configurations of Mp3Tag, one for my music collection (UTF-16 tags) on my hard drive and one for mp3's that I've converted for my car stereo which needs Iso compatible tags in order to display tags. This way I don't need to reconfigure Mp3Tag whenever I want to tag mp3's for my car stereo.

There is a basic version that comes for free (with restrictions) and a full featured paid version.

 

Thank You, I wound up uninstalling the newer version. Installing the older which has the option of where to install. The newer version does not have this option.
So I installed the old version to a folder name unlike the default, then let the newer version do its thing..
I'm good now, thanks.
