Could_not_load_file_or_assembly_Terrasoft.WebApp.Loader”_after_Local_Installation

Hi everyone,

I am installing Creatio 8.1.2 Studio (Softkey, MSSQL) locally on Windows, and after completing the installation, the site fails to load with this error:

Could not load file or assembly 'Terrasoft.WebApp.Loader, Culture=neutral' 

The error points to this line in web.config:

<add name="FileWebEventProvider"
     type="Terrasoft.WebApp.Loader.FileWebEventProvider, Terrasoft.WebApp.Loader, Culture=neutral" />

🔍 What I checked so far

I searched the installation folder and could find only:

Terrasoft.WebApp.Loader.resources.dll

But the main assembly:

Terrasoft.WebApp.Loader.dll

does not exist anywhere in the installation folder, including:

  • /bin/
  • /bin/en/
  • /bin/kk-KZ/
  • All language folders

It looks like only resource DLLs were included in the installer, but the core DLL itself is missing.

❓ My question

Has anyone faced this issue before?

  • Is this a known issue with the Softkey / Studio version of Creatio?
  • Should the installer contain Terrasoft.WebApp.Loader.dll by default?
  • Do I need to reinstall or download a different Creatio package?
  • Can this DLL be restored manually from another installation?

Any help or guidance will be really appreciated. Thank you!

Hello,

Seems like you either have no Terrasoft.WebApp folder or some files in it missing. Try to request proper binary files from our support.

One more idea is that your IIS user doesn't have access to this folder. Try to distribute full control rights to 'everyone', restart the website and flush redis.



Best regards,
Alina

Alina Yakovlieva,

Hi Alina, thanks for your response!

The installation package I am using is working correctly for my colleagues, so the issue doesn’t seem to be with the installer itself.

However, on my system, after extracting the setup ZIP file, the IdentityService folder appears as a compressed (zipped) folder instead of a normal folder. Because of this, the files inside it (including required binaries) are not extracted to the Terrasoft.WebApp and related folders.

I believe this is the reason why some DLLs like Terrasoft.WebApp.Loader.dll are missing during runtime.

What I have tried:

  • Extracted using 7-Zip
  • Extracted using Windows “Extract All”
  • Unblocked the ZIP file before extraction
  • Tried extracting to a simple path (C:\Creatio)
  • Ran extraction and installation as Administrator

But even after these steps, IdentityService is still showing as a ZIP after extraction, which means the folder is not being unpacked properly.

Request for guidance:

Could this be due to:

  • Windows ZIP extraction limitations?
  • Corrupted download?
  • A packaging issue in this specific Softkey version?

And what is the recommended way to correctly unpack the IdentityService folder so the missing binaries get placed in the Terrasoft.WebApp\bin directory?

Any suggestions to fix the extraction issue would be really helpful. Thanks!

how_can_I_trigger_validation_only_after_the_lookup_value_and_its_related_attributes_have_finished_loading

Hi,

I am implementing a custom validator in a Freedom UI modal page.
The validator needs to compare Pickup Quantity with two lookup-related attributes:

  • UsrTotalPendingQuantity
  • UsrPickupLimitPerDay

These are loaded through ForwardReference in the data source.

Inside the validator, when I try:

 

model.get("<attributeName>")

the values are undefined, and console shows:

 

Model not ready
Pending/Limit not loaded yet

So the validator runs before the ForwardReference attributes are available.

My question:
What is the correct way in Freedom UI to access lookup-related (ForwardReference) attributes inside a validator?
And how can I trigger validation only after the lookup value and its related attributes have finished loading?

Thanks in advance

Hello everyone, 

According to Regular Update Package 8.3.1 for Creatio Products | Creatio there have been changes made to the Creatio Architecture with Version 8.3.1:


Schemas like personalized "Environment dashboards" (great feature!!!) will be now saved by default in "Environment Schemas" of the Configuration Section. 


 

Unfortunately, for the O.G. "Custom" - Package there is contradicting information in the Academy and I wasn't able to find any more information in the Release Notes (8.3.1 Twin release notes | Creatio Academy) or the Change Log (8.3.1 Twin changelog | Creatio Academy). 

Did anyone use the "Custom" Package in Creatio 8.3.1 for smaller Customizations yet extensively ?

Is it truly behaving like a regular user-made package, or did you encounter any issues or restrictions with e.g. transporting changes, moving functionality between packages, or similar?

Regards,
David

I require assistance implementing a quiz on a Creatio Landing Page designer.

The goal is to capture both the quiz questions and the user responses for every question within the "Submissions" object list.

Creating lookup fields on the FormSubmit object did not successfully capture the questions.

Please advise on the correct technical solution for capturing both questions and responses accurately.
