Problem with the Propeller Tool on Windows10 (solved but alive again after consecutive w10 update).

I hate MS Windows.
Yesterday I've come across this bug. I needed the Propeller Tool to check something out. I have downloaded and successfully installed it on a Win10 box. No errors on installation. It opened ONCE and everything was fine. Then today, same Win10 box, nothing changed, it wouldn't start.
It tried but died soon after, never completing the opening stage.
I got these screens, the second one took me several tries to capture the instantly disappearing error. From now on I am to hate Windows even more. Needless to say I had NO chance of clicking the bug link as the error window disappears in a split second.
Any Idea what causes this behavior ?
First this for two seconds:

    Hi @Maciek,

    We've been seeing this recently. There appears to be a bug in Propeller Tool that wasn't obvious until a more recent update in Windows 10. We're still trying to find the source of the problem as it's very elusive. When the problem occurs, it's due to something that is stored in the Propeller Tool's registry settings that causes the start-up failure.

    Here's the workaround you can use to solve it for now:

    • Run Registry Editor

      • Click into the search field on the task bar, type "regedit" (without the quotes), and press the ENTER key
    • On the left pane, click the arrow to the left of the following folders to expand them; Navigate to HKEY_CURRENT_USER\SOFTWARE\ParallaxInc\Propeller\2.4.0

      • NOTE: I think it will say 2.4.0, even though the version you're running is later. If there is a later-numbered folder, choose that one.
    • Click on that last folder (2.4.0, in my example) to select it; you'll see the right pane fill with values.

    • Now right-click that folder again (2.4.0 in my example) on the left pane and select Delete

      • IMPORTANT: make sure that only that folder I've been talking about (2.4.0 in my case) is selected (highlighted).
    • Choose Yes on the confirmation dialog

    • Rerun the Propeller Tool
    • It should start right up without problems
  • Jeff, you've been most helpful. THANK YOU !!!

  • You're welcome. Glad it helped.

    Thanks Jeff. This just happened me today after an update yesterday. Thanks for a fast fix!

  • You're welcome, Publison. I've spent hours chasing this "rabbit" only to find it disappears the moment I'm about to nab it. It has all the signs of being a pointer/memory access issue that is showing up outside of where the problem is actually caused. Maybe I'll find it using the software or techniques suggested here in the forum as soon as I can get back to it.

    I could not grab the error because it went away in 1/2 second. Glad @Maciek got a screen capture of it.

  • It's been like quantum physics... I've been able to duplicate it, set up tests and repeat them successfully, narrowing down behavior, data, and code involved, but if I try to debug (measure) too close to where the problem seems to blow things up, the problem simply doesn't occur at all. Poof! No problem. It's magical and deflating at the same time. I'm sure when I find it, it will all make sense.

  • @"Jeff Martin" Bad news.
    Another win10 ubdate broke the Propeller Tool again. I haven't run through your magic recipe yet again but this time the bug seems more nasty than before and as hard as I tried i couldn't make a usable screenshot. Not even one.
    I'll try to fight the problem tomorrow.

    @Publison - is it the same in your case this time too ? Would you care to check and report back if and when you get a chance ?

    Thanks.

  • Guess I got "lucky" again and managed to capture the error msg. Same s.., as they say so here we go again. Do not even bother. I know what to do :). Thanks.

    I have not updated since Windows 10 Home 21H1. Just check and it's the current one for me. I can open the Prop Tool with no problem.

  • The solution to this problem is simple: disable Windows updates! :)

    I've hewn to this protocol since Windows 98, when an automatic update rendered my computer unusable. I'm currently running Windows 7, as supplied with my work PC, and have no regrets about my no-update policy.
