PuttyCM – Object reference not set to an instance of an object error

Problem Solved

I was recently introduced to PuttyCM and am hooked to it till now.

Just a while ago while I was making some changes to the config and all of a sudden I could not access the software. Unexpected Error “object reference not set to an instance of an object” shows up and I can’t seem to access the software anymore.

PuttyCM Error

Then I remembered the last I changed was the “Show Tray icon” option to disabled.

I re-enabled the option and…

Bingo.. I can access the program again.

Hope this will help you too. 🙂

  1. What a stupid checkbox, as the error message says:
    Unable to find PuTTY sessions (registry key ‘HKEY_CURRENT_USER\Software\SimonTatham\PuTTY\Sessions’ does not exist)

    Thanx man you really saved me !

  2. Why on earth would showing the icon in the system tray cause an object reference error?! That does not make any sense… is that just a programming bug?
