App running in background is interfering with dotnetfx install

Hello there:

as the title states a program apparently running in the background is preventing the offline install exe for framework 3.5 from executing.
Now I just recently reinstalled *10* as the prior op/sys wasn't capable of displaying the calendar, my deleting the windows store and the mail app was the culprit.
now with a fresh op/sys I have run into an issue where any Microsoft program is being stopped short by........



have no idea as to *what* app is looking for this program, but windows insists on not installing the exe that is on the hard drive but instead wants me to go to the update store.

any suggestions as to what to disable to prevent this in the future?
I've gone into Administrative Controls/Services & shut down update altogether........

For whatever reason the op/sys insists on reaching out to update to dl this web based upgrade (one does NOT get the full exe file dl'ed to their computer).
Why would one need to do that when the full exe file for what's being called for is right there on the hard drive & that's what is trying to install?

I can't seem to get around this & it is annoying, the previous system that had store removed, all of those default installed apps removed didn't do this.
I get the impression that I'll have to use powershell to one by one remove the offending app program that's causing this.

It's not framework 3.5.

The program I make use of that is built on 3.5 is a video editor (Vegas),

yeah, I don't see why there would be an issue here as well, 3.5 is a Microsoft program, the op/sys is being flat out fussy.

from what i can tell the dotnetfx x64 version is there but not the x86 version of 3.0 .. just giving my thoughts. but a have a nifty little program i got from ms long ago if you find it usefull . it dotnetfx repair tool . here is the link.

quite true, I am using an older version of (Sony) Vegas that predates the transition to Magix,

Magix will not accept the old Sony products update to Magix products free of charge. There is a fee involved & as such I do want to pay out that hefty fee.

When one begins to allow the op/sys reaching out to the upgrade store one doesn't get the full netfx exe downloading to ones hard drive, instead the system will begin remotely installing netfx.
In this manner there never is an actual install into the op/sys on the hard drive that is registered into Programs & Features ...or whatever 3rd party Uninstaller one may use.
I don't do this at all.......I always install any program via the offline full exe, I keep these program install exe's in my ever growing collection.
