I don't think the problem is at MS end or anything to do with accounts, it is at local machine end, here's why;
My setup;
- Desktop with one primary MS account and two non MS accounts, secondary account and my wife's running Windows 10.
- Laptop with same primary MS account and my wife's account, again running Windows 10.
MS jigsaw running on the desktop primary account only.
Yesterday opening jigsaw on the desktop primary MS account came up with the message 'microsoft jigsaw is currently not available to you'. Tried everything I could find on the web to get it started to no avail. Went to laptop to run it there but forgetting that it wasn't installed. Tried to install on the primary MS account on the laptop. Install failed when obtaining the licence with message 'something went wrong, we'll try again', error code 0x803f8001. Continued to try to fix both machine's, but failed. In the end decided to uninstall jigsaw from the desktop primary account. On reinstall received the message 'something went wrong, etc.' when acquiring the licence, same error code.
So went to my secondary (non MS) account on the desktop and tried to install jigsaw, success, ran the app, no problem. Then went to my primary (MS) account on the desktop and tried to reinstall jigsaw again, this time successful, Ran the app, again no problems. Back to the laptop, tried to install, failed. Went to my wife's non MS account and installed jigsaw no problem. Back to the primary MS account a new install was successful.
So pick the bones out of that lot.....
Same account used on two machines, app failed on both machines using that account. The fix, to use a different account to install the app, then reinstall the app on the initial account. But process had had to be done on both machines. So it's not an account problem. Neither is it an OS problem as we don't use the laptop that often and Windows hadn't been updated with the latest (June) build.
