Can't install or uninstall Labview

[Chanlon]

When I try to install LabView I keep getting this error and I can't uninstall the software to reinstall it as it says the uninstaller cannot be found. 
Any help would be appreciated. Thanks

It seems like something in your NI Package Manager (NIPM) installation has gotten damaged. My suggestion is to:

1. Uninstall NIPM by going to Control Panel, Uninstall a Program, choose "NI Package Manager", then Uninstall it. Follow the dialogs to remove it. Note that it will not remove any other NI software.
2. Download and install the latest NIPM installer from here:https://www.ni.com/en-us/support/downloads/software-products/download.package-manager.html
3. Try your LabVIEW installation or uninstallation again.

Just tried that, no change. Same error

Which LabVIEW version are you trying to install? With the older ones that came on disk and USB drive, you could force a reinstall by navigating to the folder with the installation files (as administrator in command prompt) and running the following:

setup.exe /reinstall

That doesn't help us because we have no idea what you think is the latest version of LabVIEW.

That's not a valid LabVIEW version format.  I don't want influence your response by making a suggestion, so could you correct yourself and reply with the version you consider to be the "latest"?

Thanks.

Do you mean LabVIEW 2020 SP1?   Because 2021 hasn't come out yet, and "SP" never comes before the year.

A word to the wise -- I had no trouble installing LabVIEW 2020 (not SP1).  However, when I attempted to install the SP1 update, it was extremely difficult, and took over 4 hours.  I have over a decade of experience installing LabVIEW, and have written a number of Posts on the Forum about my experiences installing and uninstalling LabVIEW since NIPM was introduced.

So my advice would be (if it is at all possible to do this) to (a) uninstall all National Instruments Software (there is only one "safe" way to do this, described on a number of Posts and also locatable with a Google search), then install LabVIEW 2020 (I know LabVIEW 2020 installs OK, and suspect LabVIEW 2020 SP1 might install better if on an NI-Software-free Windows system).  I recommend installing 32-bit LabVIEW (mainly because "that works for me" and might be a little more "stable").

Tips on how to have a successful NIPM Installation of LabVIEW have also been posted many times on the Forum (by myself and others).
