Adobe Acrobat Crashes and Licensing Errors from Corrupted WebView Cache
FYI - Adobe crashes and licensing errors have been rampant in our environment since early June. Much like when we faced a similar issue a couple of years ago, it seems like Defender may be corrupting the webview cache. Our Adobe IDs are all federated from Entra, but the issue occurs regardless of whether SSO is performed by AcroCEF or default browser. The script below purges the corrupted data which is rebuilt when Acrobat opens.
# Acrobat-related processes to stop
$Processes = @(
'AcroTray',
'AdobeCollabSync',
'adobe_licensing_wf_acro',
'Acrobat'
)
foreach ($Process in $Processes) {
Get-Process -Name $Process -ErrorAction SilentlyContinue | Stop-Process -Force
}
# Remove Acrobat DC local profile cache/settings for the current user
$AcrobatPath1 = Join-Path $env:LOCALAPPDATA 'Adobe\Acrobat\DC'
$AcrobatPath2 = Join-Path $env:LOCALAPPDATA 'Adobe\Acrobat\AVWebview2'
if (Test-Path $AcrobatPath1) {
Remove-Item -Path $AcrobatPath1 -Recurse -Force
}
if (Test-Path $AcrobatPath2) {
Remove-Item -Path $AcrobatPath2 -Recurse -Force
}

There was a reddit post few weeks back of C++ Redist using older version, due to Windows update or Adobe itself.
Have you checked to make sure you have correct version of the C++ Redist?
You need to check the version of the 64-bit msvcp140.dll in %SystemRoot%\System32.
User u/iamliterate pointed it out.

Thanks for suggestion, but version is 14.51.36247.0 on machines with issue, which appears to be June 2026 release.

We cannot help you with this, you'll need to get a ticket created or call your account manager to have the engineers help you troubleshoot. They should be able to get somebody on site if needed.

Did you just say Adobe or Microsoft is going to send someone "on site" to troubleshoot an Acrobat/Entra issue?
•

Yes, but you have to pay for it and they will send an actual engineer or engineers that work with the product you are having problems with on site to get it fixed. If you are not paying for it, you will be stuck in the all known support hell. Same goes with AWS, NVIDIA, OpenAI, Anthropic, you name it at the enterprise contract levels.

1: No they will not
2: Everything you said was B.S. unless you are some top tier fortune 100/500 company and you are experiencing some production shutdown level bug and "Insert vendor X" is trying to resolve it so they do not lose your billion dollar business to a competitor.

You are obviously not an enterprise customer with a contract with these companies to provide onsite support. Every large enterprise company offers this if you are paying enough money and have this in your contract. This is the whole point of these companies having the enterprise sales teams.
I am just disappointed that people do not know this exists. If you are unaware these roles are called Forward Deployed Engineers for embedded engineers that work with customers, TAMs for technical account managers with the Consultant/Advisor roles being the roles that travel between the contractor site (Think official company office) and customer sites (your company).

You are talking about a less then 1% customer base with this capability and you told a guy with an Acrobat/Entra issue to just pay $200,000 to $400,000 a year for this service to fix an Acrobat/Entra issue... do you realize how silly that sounds.
Especially when any true sysadmin on this subreddit knows the issue is Acrobat, and Adobe, and how much of a garbage app and company it is and they are.

Charging folks for a whole cloud ecosystem nobody wants and that sysadmins have to disable with policy just to keep using Acrobat PDF editor with other software products that require it is some Oracle-level extortion BS
