ArcGIS Pro 3.5 installer does not recognize WebView2

[RichardDaniels]

We have deployed ArcGIS Pro 3.5 to 900 computers, of these about 800 installed without issue with the remaining 100 failing. Message shown is the 'Microsoft Edge WebView2 Runtime (x64) version 117 or later...you must also install WebView2 Runtime as per-machine. " We are currently at WebView 148.0.3856.84 -the current version. 

On checking the package, ESRI is looking specifically for HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\EdgeUpdate\Clients\{F3017226-FE2A-4295-8BDF-00C3A9A7E4C5} and HKEY_LOCAL_USER\ Software\Microsoft\EdgeUpdate\Clients\{F3017226-FE2A-4295-8BDF-00C3A9A7E4C5}.  In the ones that fail the GUID shown is in HKEY_LOCAL_MACHINE is present. 

Have anyone else seen this issue at this scale? Given that 10% of our machines have failed, it is more than just a 'bad' install of WebView2 (which the March 20, 2026 release of  v148.0.3856.72 was, replace by v78 on March 23rd ;-)). 

Insite's are welcome.

One option we are considering is just editing the ArcGIS Pro msi and change the signature that it is looking for from HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\EdgeUpdate\Clients\{F3017226-FE2A-4295-8BDF-00C3A9A7E4C5} to

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\EdgeUpdate\Clients

This would mean the install would still look for and require WebView2 -but it would not be depended on finding a specific GUID.
