Could not load file or assembly 'ScintillaNet.dll' or one of its dependencies.

Cannot get past this assembly load error and it is extremely frustrating when you are trying to evaluate a product. Trying to set Activity Event per First Workshop - any thoughts?????

Full context as follows:

Studio Console

Could not load file or assembly 'ScintillaNet.dll' or one of its dependencies. The application has failed to start because its side-by-side configuration is incorrect. Please see the application event log or use the command-line sxstrace.exe tool for more detail. (Exception from HRESULT: 0x800736B1)

Windows Event Log

Activation context generation failed for "C:\Windows\assembly\GAC_64\ScintillaNet\\ScintillaNet.dll". Dependent Assembly Microsoft.VC90.CRT,processorArchitecture="amd64",publicKeyToken="1fc8b3b9a1e18e3b",type="win32",version="9.0.21022.8" could not be found. Please use sxstrace.exe for detailed diagnosis.


Per other forum posts - have tried a number of different versions of C++ Redist - no luck.

Flushed all temp locations per KBs - no luck

GAC exists - version identical to one in Studio folder

Studio 11 install on 2008 R2 SP1

We look forward to hearing from you



- Project is .NET - we are following the 1st lab step-by-step.

- Latest binaries - 11.

- As stated, 2008 R2 (only comes in 64), Studio is 64

- Studio installer laid down .NET (4.0.30319) but we did run all updates from MS

- Libraries listed in attached screenshot - we have tried all combos 2008 forward.

For what its worth, we installed Studio on W7 x64 and issue was not present.


Dear Pierre,

Thank you for your feedback. In order to solve this issue, we recommend to reinstall the latest version from:

If the problem continues with this solution, then you need to desinstall and install all component, .NET Framework and Studio like a clean machine.

We look forward to hearing from you
