Question about thumbnails

Krisidious

logical ThumbsUp.dll it's value is {A86C8053-587B-4DFB-A5E2-54E9803E4463}

That is the "illogical" dll !
If you do a find based on that string, it takes you to a Layout path !
There are two of these dll files supplied with a SketchUp installion, one in the Layout folder and another in the SketchUp folder.
One might have thought that the SketchUp folder one would be referred to regarding SketchUp's SKP thumbnail display, and not the Layout one - although they do appear to be identical !
This odd path is set up like this in v2015 and v2014 !
The string '\ThumbsUp.dll' only ever appears in conjunction with a 'Layout' path, AND it is linked back to SKP etc...
It never appears connected to SketchUp directly !

Mine is set correctly and I got it the day it was released. I don't recall any updates as of yet. I'm on Win 7 Ultimate 64bit.

Sorry Tig... I messed up that screenshot somehow. look again. I fixed it.

CLSID has a default value of {A86C8053-587B-4DFB-A5E2-54E9803E4463}

be it logical or not I have no idea. I do have thumbnails in Explorer, SU Import and SU Open/Saveas though.

TIG

That {A86C8053-587B-4DFB-A5E2-54E9803E4463} refers to the ../Layout/ThumbsUp.dll, which seems illogical as it's setting up a SketchUp SKP thumbnail AND there is a ../SketchUp/ThumbsUp.dll
It works but it makes no sense !

Krisidious

Forgive me if I'm wrong, but Layout in 64 bit had thumbnails in 2014 and 2013 didn't it? i can't check it now that 2015 is in. Could they have routed them to fix the issue? I downloaded the update, I'll check it again after I install.

Trimble supply copies of the ThumbsUp.dll in both the Layout AND SketchUp folder, but the Registry only ever refers to the Layout folder version - but it's not just for .layout file type:
HKEY_CLASSES_ROOT\.layout\ShellEx\{BB2E617C-0920-11d1-9A0B-00C04FC2D6C1}
But also for SketchUp .skp files too:
HKEY_CLASSES_ROOT\.skp\ShellEx\{BB2E617C-0920-11d1-9A0B-00C04FC2D6C1}

Since it all works it's not so critical, but it just begs the question why it is set up like this ???

Changing the path to look in the SketchUp folder fails to make thumbnails, but the Layout folder version works fine. Both dll files are identical in their code !

Thanks guys, and though I have no real idea what the previous few posts are all about, I was able to confirm that my settings "{A86C8053-587B-4DFB-A5E2-54E9803E4463}" are correct. Which is a bummer, as I still have no thumbnails. But thanks again for the effort.

You can try to rebuild your Windows icon cache (in Vista, Win7, Win8) - worked for me with missing icons in the start menu (Win7):

Close and save anything that you are working on. This command will kill explorer and restart the computer when completed.
Open the command prompt (cmd)
In the command prompt, Copy and paste each command line below exactly as is one at a time and press enter after each command.

WARNING: The last command will restart the computer, so be sure to close and save anything that you are working on first.

ie4uinit.exe -ClearIconCache
taskkill /IM explorer.exe /F
DEL "%localappdata%\IconCache.db" /A
shutdown /r /f /t 00

The IconCache.db file has now been rebuilt.
