retrieving old intunewin files

Hi All

So I made a mistake

We wanted to move from an purpose built intunewin installer of Citrix workstation to the MSStore version so it would update. 

However, just a few hours before, I wanted to try using a new intunewin file to update the app, then my boss decided on the stores well.

I had already replaced the intunewin on the intune apps installer page, and I must have either copied over it by accident or, I don't put it down the memory hole, but I can't find it now.

We are now getting errors trying to uninstall the old app with saying unzipping issue. Online I see it can we a problem with the intunewinapputil.exe. I did update the intune builder app as it was having the crashing terminal/cmd/ps issue that I built the new one with.

I'd very much like to roll back my intunewin file, but as I said I can't find it.

Is there any place these installers are saved? 

I can just use the old app builder with the older version of the app, and try that, but I was really hoping to use the original.  As it is just the msi in a wrapper I assume that will work, but who knows with MS>

Thanks
