Runtime engine 8.0.1 does not install because higher version is installed

[fbellay]

Hello,

I am trying to install Runtime Engine 8.0.1.

This is the message I get when installing Runtime Engine 8.0.1:

"A higher version of this product is already installed."

Yet I do not have another Runtime Engine version installed. According to the NI Add/Remove program, I have the following installed:

NI LabWindows/CVI 8.1 Run-Time Engine

NI Measurement  & Automation Explorer 4.2.1

NI-488.2.2.5

NI-485x Software 1.0.1

NI-VISA Runtime 4.0

At some point,  I un-installed:

NI LabWindows/CVI 8.1 Run-Time Engine

NI-488.2.2.5

but I ended up with the same results:

"A higher version of this product is already installed."

I checked my folders and deleted any trace of Runtime Engine folders. I therefore deleted:

C:\Program Files\National Instruments\Shared\LabVIEW Run-Time\

but I am still unable to install Runtime Engine 8.0.1.

Any idea?

Thanks,

Francois

Hi Francois,

If you have a newer version of the runtime engine installed, then it should be listed in MAX. However, you've already deleted that directory, so it may not be there anymore. The only way now to uninstall those versions of the runtime engine is to use a utility we have that I cannot post on the forum. If you can create a service request via email or phone then we would be able to help you get the newer versions fully uninstalled. You can create a service request at www.ni.com/ask.

If you do not have a support contract and cannot create a service request, then let me know and I will create one for you so you can call in.

Hello Rick,

We do not have any service contract at this time. Could you create one so we can download the fix for this problem?

I submitted a bug to NI last Friday, but I haven't heard anything from them so far. (Reference#7170129)

Thanks,

Francois
