Question about thumbnails

TIG

Tig, yours was set incorrectly during factory install? Or it just happened somehow?
It was just wrong 'somehow'.
I did NOT initially get any thumbnails in v2015 64bit, but that Registry tweak fixed it.
Obviously, I had not previously been getting thumbnails in 32bit v2014 on the 64 bit PC as they are not compatible...
If I recall that Registry entry was either not set up with any 'value', or perhaps it was referring to a wrong 'value' - I can't recall - anyway, it now works !
It's odd that the ThumbsUp.dll path that is referred to in the convolutions of the Registry is to the one in the Layout folder rather than then one in the SketchUp folder - but I see it's the same in v2014 too...
What values do you get for that Registry entry?
I think they are common across 64bt PCs...

But, I bet you were Beta huh? you could have had an old install of 2015 put something funky in.

I'll check mine.

Currently, I have large thumbs for any newly saved files, but all small thumbs for older files. Need a batch program to update all the thumbs.

2015M1 is out in the download area - a poor-do by Trimble who have failed to announce it for three days !
Does your SketchUp.ShellExtension point to the logical ThumbsUp.dll or the Layout one ?
Under CLSID ?

Krisidious

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

TIG

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.

TIG

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.
