GUI Issues

GUI crashes

53 views 0

Problem:
Under some circumstances the Personal Printing GUI may crash when selecting the “Personal Printing” tab and a “Default user PIN” was set in Personal Printing (see image below).


Cause:

The default user PIN will be encrypted and stored in the following registry key.

HKLM\SOFTWARE\ThinPrint\TPFMExt\
DefaultUserPIN (REG_SZ)

Every time the “Personal Printing” tab is selected, the PIN needs to be decrypted. This might fail on some systems due to a bad implementation of the decryption algorithm

Applies to :

Personal Printing (any version)


Workaround:

You can work around the issue by removing the default user PIN.

 

Solution:
Replace TPFMExt.dll with version 3.0.315.x or higher.

  1. Rename old TPFMExt.dll in %ProgramFiles%\Personal Printing\
  2. Copy new TPFMExt.dll to %ProgramFiles%\Personal Printing\
  3. Finally restart the server
