No fix for persistent 191 error
I have been granted access to Creative Cloud by my college IT course for web development. I can install the apps I need as follows: Creative Cloud desktop app, Photoshop, Bridge, Dreamweaver and Illustrator; all except XD which gets to 100% of the install then fails with error code 191. In addition, the CC desktop app itself fails to update with the same error.
I have an administrator account. I have tried all 5 solutions outlined here: https://helpx.adobe.com/download-install/kb/error-code-191.html to no avail. I have completely uninstalled all apps, including the CC desktop app itself, run the AdobeCreativeCloudCleanerTool, and reinstalled from the ACCCx5_10_0_573 ZIP file (reinstalling from Creative_Cloud_Set-up.exe from the website, or through the Microsoft Store, gives the same result; I tried). I get the same error in every situation. I even tried installing with both anti-virus and firewall turned off to no avail.
The information for error code 191 on this site is completely opaque and none of the suggested solutions work. I know it is some esoteric permissions problem because I can install and update using the built-in Windows 10 Administrator account. This proves the point, but is not a solution since this account is inherently unsafe, only meant to be used for troubleshooting and, in any case, any CC apps installed under this account are unavailable to other users.
Please can someone point me to where I can find the error logs for CC apps installation (in Windows 10) and where I can post them for more expert perusal, so I can resolve this extremely frustrating issue.
