Upgrading moodle 3.5.5 to 3.5.12 and encountered the following error while performing command line update in Windows/IIS server. "Invalid permissions detected when trying to create a directory. " (More detailed errors included below.)
-tried deleted cache folder contents, no luck
-tried adding IUSR with Full access to cache folder, no luck
-tried web interface update, no luck, blank page after a minute
-added myself to cache folder with full access, helped,
-added myself to localcache folder with full access, helped
-added myself to whole moodledata folder, appeared to work then.
Solution: add access permissions to moodledata for the account I was logged into the server with.
The CLI process must be running under my user account, not the web user. To further complicate things my administrator account didnt seem to have enough access rights to the moodledata folder on a network drive, so I added myself, perhaps the network drive was part of the confusion too.
Thought Ild post my solution for Windows 20016 IIS 10 users out there. There's a few forum posts on this issue with apache solutions.
