An Internal Error Occured and Tools not showing

[default0ps9imd6u529]

Hi,

When trying to open the File menu or click on the page zoom button in Acrobat Pro DC 64-bit (win10) I am getting a pop-up that says "An internal error occured". I click 'OK' to clear the pop-up and it just appears again.

The other error I am getting is that none of the tools are showing on the tools tab or in the tools sidebar.

I have tried reparing the installation, uninstall/re-install and even running the AcroCleaner, with no luck.

I believe the error first occured after I clicked the 'dock' option on the new annoying floating toolbar that recently appeared, as I wanted to move the page view and zoom options back into the top bar.

Any suggestions will be appreciated.

Hi Guys

A solution that works was posted on 17th Nov by AndreX86. Reposting it here. 

I was using Acrobat Cleaner tool to remove the existing files, except the cleaner tool is not removing all faulty files/folders. Need to manually remove them. Once done, you can reintall and it should work. See below and thanks AndreX86.

Encountered this issue. Nothing specific mentioned fixed the issue. I had to do the following to completely resolve the issue. 

1.  Use the AcroCleaner to Uninstall Adobe > https://www.adobe.com/devnet-docs/acrobatetk/tools/Labs/cleaner.html
         a. Reboot afterward
2. Go to Control Panel > Programs and Features; Uninstall anything named "Adobe" 
3.  Open an explorer window and type %appdata% and press enter. Go into each folder (Local, Local low, Roaming) and delete any folders named "Adobe"
4. Go to C:\Program Files\ and delete any folders named "Adobe"
5. Go to C:\Program Files (x86)\ and delete any folders named "Adobe"

After you've done all that try re-installing Adobe. 

Hope that helps."

I did all of that and the reinstall worked for about 2 days and the error popped back up and my tools are gone again.
