Adobe Acrobat DC sign in blocked by GPO

[toby5C5C]

Hi,

We have Adobe Acrobat 21 for some of our users.

No issues with install but when launched, sign in fails and reports 'Update Required - your browser or operating system is no longer supported'.

As seen here:

Update your operating system to work with Adobe apps

None of the fixes there worked.

After some investigation, we worked out that Microsofts secuirty baseline 'MSFT Internet Explorer 11 - Computer' is causing the issue as when we turn the gpo off in a test OU, Acrobat sign in works fine.

With a lot of settings to go through, can anyone narrow down what setting/settings will be affecting the sign in process?

Thanks.

Are you sure that the acronym is GPO?

Maybe the GPU, graphics processing unit on a computer?

Yes, GPO means Group Policy Object.

OK, thanks. That's new one for me. <grin>

One of my collegues working on thbis issue has narrowed down the GP setting in the MS baseline that caused the issue.  This setting has been disabled by an over-ride gpo with an AD secuirty group linked for only those users that need the secuirty lowered.
