LoadError 127

The Error

After installing FlexTools and restarting Sketchup you may get the following loading error:

Error: #<LoadError: 127: The specified procedure could not be found. - C:/Program Files/SketchUp/SketchUp 2018/Tools/RubyStdLib/platform_specific/openssl.so/>

Explanation

Another application has installed the following two OpenSSL libraries which are apparently conflicting with Sketchup's libraries:
C:\Windows\System32\ssleay32.dll
C:\Windows\System32\libeay32.dll

Because of a bug in Sketchup, SketchUp is trying to load the files from C:\Windows\System32\... first, instead of trying to load its own, up to date libraries, from C:\Program Files\SketchUp\...

The error is happening because these two files have an older version than SketchUp requires, and FlexTools needs these files for it's own operations.

Solution

  1. This bug seems to be finally solved in Sketchup 2019 !  Consider upgrading!
  2. As workaround, if you are using previous Sketchup versions (2017,2018) we propose to install the latest versions of the OpenSSL files from a 3rd party website
  • Note that this solution doesn't not always work.  We've had some customers report success.  Other customers eventually updated to Sketchup 2019 which solved the issue.

We do not take any responsibility over the contents of the files below.

Scan them for viruses.  Continue at your own risk!

 

Install Procedure

1. Understanding the possible risks, download the latest OpenSSL libraries:

1.1.0j Light - https://slproweb.com/download/Win64OpenSSL_Light-1_1_0j.exe

 

2. Install with Right Click > 'Run as administrator'.

 

3. Windows will probably warn that this installer is from an 'Unknown publisher'.  In this case click 'More info' and after that 'Run anyway'.

Open SSL installer window screen1
Open SSL installer window screen2

4. Then install it as usual.  Make sure to check 'Copy OpenSSL DLLs to The Windows system directory'.

Open SSL installer window screen3

5. After installation it may ask you for a donation for the OpenSSL project.  Make sure to uncheck all check boxes so it won't open you browser (unless you wish to donate to the developers at slproweb.com)

 

6. Run SketchUp.  Hopefully the 'LoadError 127' will go away and FlexTools will run normally.

 

 

* If for some reason, the error message comes up again - it is probably because another application installed the older libraries again.  You will need to follow the steps above to resolve the issue.  If you happen to find which application is installing the older libraries, Please let us know.

 

** If this installation doesn't help to solve the errors coming up, you can try to follow the steps again with the following previous installers:

1.0.2r Light - https://slproweb.com/download/Win64OpenSSL_Light-1_0_2r.exe

Or an even older version:

1.0.2p Light - https://drive.google.com/file/d/1hxyWg-9Kc-UP2K8_QG6BXB7kQSN12uUG/view

 

*** If neither solution works, our best recommendation is to install Sketchup 2019 which apparently has the bug fixed.
