I have been getting notifications that an update to Creative Cloud is available. However on trying to install the update I was repeatedly getting could not install error 191 messages. I uninstalled CC and tried to reinstall. Would not install. I tried the steps contained for 191 errors - most of these steps failed. I also got C500 errors on occasions. I found via this forum and alternative installation file. It installed very quickly but then it tried to update and the original errors were repeated.
What should my next be be to update the CC?
Thanks for any help,
Jeff (Windows 10 Pro Build 1909)
JeffNK, error 191 occurs because the installation is being blocked. Error C500 also indicates a similar problem with the package not being able to be installed.
Please review the settings for any installed software firewalls and security software. C500 can occur because Windows Defender is blocking the installation. Error 191 can occur if security software is blocking the install process over the network.
For more information on both errors see the following:
I have uninstalled my BitDefender firewall togeter with associated virus check etc. Windows Defender Firewall reports as off. Howver error messages persist.
I updated my Windows 10 to Build 2004. This seems to have resolved everything. I am not sure that a cause of my difficulties was not Windows ie Defender Firewall which seemed to resist all attempts to implement solution options I found on the Adobe website and elsewhere.
Thanks for the update on your resolution, JeffNK.
My best practices when starting to use my Windows computer, every day, is as follows:
This workflow seems to have worked fairly well and I seldom run into errors while running Windows 10 Professional on my home computer. I will also periodically run a utility provided by the computer manufacturer to verify there are no driver or BIOS updates also available.
Spoke too soon. Now Microsoft 365 doesn't work. Had to roll back Windows 10 2004 install and put up with previous errors.
I am sorry to hear that, JeffNK. It does sound like you are encountering several problems with the current installation of Windows 10. I would recommend you double check your back up in case any additional errors occur.
