Creative Cloud update install errors.

Question

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:
