I am getting an error AMT Subsystem Failure every time I try

Resolved Question:

I am getting an error AMT Subsystem Failure every time I try to open an Adobe document. I have two licensed Adobe products on my computer (Adobe Acrobat 9 Pro and Adobe Photoshop Elements 5.0) in addition to Adobe Reader X (free downloaded reader). I tried some "patch" today on the Adobe site which did nothing.

This error forces me to close the document and will not let me print it either.

Help, thanks.

Carl :

Hello and welcome to Just Answer. My name isXXXXX can I be of assistance to you?

Carl :

Try this and let me know if this fixes your problem

Carl :

Rename the FLEXnet folder to FLEXnetold in the following location:

  • On Windows XP:
    C:\Documents and Settings\All Users\Application Data\FLEXnet

  • On Windows Vista or Windows 7:
    C:\ProgramData\FLEXnet folder

Customer: Hi Carl.
Customer: Renaming the FLEXnet folder tomFLEXnetold did not work. If it helps, inside the ANT Subsystem Failure box it says The licensing subsystem has failed catastrophically. You must reinstall or call customer support. (14)
Carl :

What I would suggest is uninstall both applications and reinstall them. If they have become corrupt this should fix them. Let me know if you can give that a try.


I will try that this evening when I'm finished working and let you know what happens next.

Carl :

Sounds good. Thanks for letting me know.


It ended up that when I went into Adobe Acrobat Pro 9, to uninstall, it gave me an option to fix or repair and I selected that option. Once that was done, the error didn't come up again.
