Unable to install KiCAD under Windows 10

If it were deleted than after unistall you would lose all your settings.

C:\Users\{UserName}\AppData\Roaming\kicad\

I did have two kicad files under AppData, one under Local and one under Roaming. I then did an Uninstall of the nonworking program, checked those locations again, and they had not been purged with the Uninstall utility, as dsa-t forewarned. So I simply deleted both kicad folders, which had some items in them that got dumped too, of course.

Then I tried the mkdir test, also per dsa-t, and got the error message shown below. BUT… I can navigate to that folder, right-click for Make New Folder, and create a KiCad folder manually. That’s the second image below the error message.

So just like the error messages I got during the several failed KiCad installations, a mkdir command, either typed into Run or from a program installer, isn’t able to create a specified folder because that folder can’t be found. This does not make sense to me at all.

AHA update! I consulted the Web and found a fix, at least to making folders with the CMD prompt. I was advised to go into Security settings and turn OFF the Controlled Folder Access switch. I did this, and then put in dsa-t’s mkdir C:\Users\Lab\Documents\KiCad test, and sure enough, I got the kicad folder under Documents (yes, I deleted the hand-made one first). This is encouraging, I’ll try installing KiCAD again. But first the boss says I have to put up the outdoor Christmas lights. I’ll be back!

Well, wonder of wonders. That simple fix did the job. Now KiCAD appears to be up and running, and also seems to have a lot of good features that I can use. The PCB layout program I have been running is more than 25 years old, and is not stable under current versions of Windows.

Thanks much to everyone; I’m sure I’ll be back.

Well done Jim - glad you got it sorted.

Controlled folder access was not normally ON by default in W10. What set it?

Well, either I did, misguidedly thinking it improved computer security, or maybe O&O’s SU10 had a switch to flip, suggesting additional security. Anyway, it’s off now and all is well.

Windows “Testing” now gives a more helpful warning message if controlled access is on
