New Instalation - Error 100700 when trying to update

[anmatr]

I have a complete new instalation of Acrobat Reader

When I click on the Help -> Check for Updates menu item I get the following error:

Update Failed

Updates have been disabled by your system policy.

Error 100700

As I had a previous installation this was not happening at all.

Further I cannot change the theme to Dark Grey, or better it does not stick - after restart its reverted.

Forgot to mention: its on Windows 10 Pro, Verson 22H2

There is no system policy in place to prevent updates at least I have never done that. Other applications update fine.

Updater checks multiple registries (EULA acceptance, LUA, bUpdater), and if any of them do not pass, error 100700 is displayed.

To find out which one failed, please follow the steps below.

Enable verbose logging for Updater, check for updates and provide (upload the file somewhere and send me private message with a link) AdobeARM.log file from User Temp folder?

To enable logging-

Set iLogLevel REG_DWORD value to 1 in the registry below

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Adobe\Adobe ARM\1.0\ARM on 64 bit OS

Hello, 

thank you for picking this up.

I've located the log file and applied the registry change but could not see any change in the log level in that file.

Here is what I get when trying the update:

[2025-07-20 12:50:26:0857] Adobe ARM 1.824.460.1110 logging started.

If I read that correct it is the EULA not accepted. How to get that working?

Thanks

BTW here the registry setting I did:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Adobe\Adobe ARM\1.0]
"ARM on 64 bit OS"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Adobe\Adobe ARM\1.0\ARM]
"iLastSvcSuccess"=dword:00003f99
"iRandom"=dword:000052b7
"iCheck"=dword:00000003

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Adobe\Adobe ARM\1.0\ARM\Products]

I do not think you followed instructions, but it is clear that EULA is not yet accepted.

Please add EULAAcceptedForBrowser DWORD registry value in the Registry path below and set it to 1

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Adobe\Adobe Acrobat\DC\AdobeViewer

Try check for updates after that.

[anmatr]

Appreciate you following up on this - thank you. I've applied now (hopefully) the correct settings for logging but don't see a change on it. Here the exported setting:

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Adobe\Adobe ARM\1.0\ARM on 64 bit OS]
"iLogLevel"=dword:00000001

But then when I applied the 2nd setting you posted it did get beyond the error and the log looks good. Updater is reporting that its "No updates available". Great - seems to work!

Here the exported setting:

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Adobe\Adobe Acrobat\DC\AdobeViewer]
"EULAAcceptedForBrowser"=dword:00000001

Thank you for your help.

Can this in any way be a security risk?

Can you please let me know if the logging setting is now correct? If so, why do I not see any further messages?

Glad it worked. There is no security risk with incorrect logging setting you have, but the correct one is below-

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Adobe\Adobe ARM\1.0\ARM]
"iLogLevel"=dword:00000001
