Well done Theodore for finding this fix. It's strange that Windows Store is a Windows app and is not fixed by SFC /SCANNOW. Is there a similar fix for Windows 8 apps which are also prone to having problems? I had various problems with my W10 upgrade (including apps) and did a clean install last week which was time well spent.
I took the precaution of making Macrium Reflect backups of the clean install immediately after the W10 installation and after installing all my apps & programs. I should have the apps folders if needed from these backups. However, what happens after a major upgrade to W10? Will the apps folders in my clean install backup and the link posted by Theodore still be valid?
The problem with this approach (rather than a repair install) is it gets fiddly. You have to not only have the correct versions of each app but the correct version of pre-requisites of that app (so you need the right versions of VClibs and .NET in C:\Program Files\WindowsApps as well).
For example Mail in 10586 has these dependancies (from the AppManifest.xml file)This could mean after an upgrade (either of OS or apps) while you could use the exact same approach - you might have to track down an updated (or older) version of dependencies (it isn't hard to identify - powershell will tell you when you try to install if you don't have it).Code:<Dependencies> <TargetDeviceFamily Name="Windows.Desktop" MinVersion="10.0.10240.0" MaxVersionTested="10.0.10240.0" /> <PackageDependency Name="Microsoft.VCLibs.140.00" MinVersion="14.0.22810.0" Publisher="CN=Microsoft Corporation, O=Microsoft Corporation, L=Redmond, S=Washington, C=US" /> </Dependencies>
If you got an ISO after an upgrade you could extract them from there I guess as the upgrade will update your apps but will not update your old backup so you would have all you needed (somewhere).
I did install windows 8 store (by copying all the files and dependancies) into one of the Windows 10 previews (because I'd uninstalled it by mistake and only had Window 8 to copy from) and it immediately updated itself but it was quite a hassle.
I do like @Thodore thinking here - it is clever. But for the future what would be nice is if MS would let you do the apps part of the repair install on its own (without upgrading everything else) as this problem does seem to happen a lot.
I think MS needs a comprehensive Apps Troubleshooter in view of all the apps problems in W10 & W8.
As far as I can figure out it checks the ownership of one directory and then gives up.
I can understand their networking troubleshooter being utterly useless (lots of different hardware and so on) but they should have control over their own programs which are delivered as part of every upgrade.
Mind you, it is my hobby so it would be dull for me if it was all too easy
Thank you both. This looks very positive and helpful, I feel at last I may have a chance of getting somewhere. If I can settle the apps and Store problem without re-installing I will be very pleased. I will start serious work on it tomorrow.
In the meantime I will explain about the Calendar. I cannot delete past or future entries, either one-off or series which have multiplied automatically making quite a mess. For a while I could not create new entries but now I can. But when I click on an existing entry I want t remove, the editing page opens but there is no delete option or other way to delete. The Live Tile has been OK.
One reason I have been wary of the re-install is this: I paid a professional (quite a lot) to do the upgrade because I feared difficulties due to the small amount of free storage space on my SSD, only 5 GB, despite spending months preparing with several strategies to reduce the amount of disc space used. I now have only about 3 GB. If I had to re-install would I face the same issue, or worse? I struggled (but succeeded} with installing the November update which was held up by messages saying my storage space was not enough.
I have just started on Theodore's Fix for the broken apps --- with a considerable amount of trepidation.
I have encountered an ERROR notification in Step 6, Setting Permission for App Packages. At the last instruction I get this message "Failed to enumerate objects in the container. Access is denied." I have gone through the procedure again, with care but with the same result."
Can someone advise please? I have only a vague idea of what the message might mean.
