Hello Enrique,
Yes, that’s correct, the version you were on is 4.8.20252.399, and the fix is available in the newer build 4.8.20261.413.
Since the httpHandlers/httpModules entries reference the assembly with an explicit Version= attribute, you’ll need to update those entries to point to the new version after upgrading. The simplest approach is to replace 4.8.20252.399 with 4.8.20261.413 in each type= string (all three entries you pasted).
It should continue to work without any changes after this update.
After updating the version strings and rebuilding, please give it a try and let us know if you run into any issues. Please share images of the issue you get so that we can investigate accordingly.
Regards,
Uttkarsh.

Hello Enrique,
→ Open my ComponentOneControlPanel (actual, not latest) is different steps
The version of ComponentOneControlPanel you have installed is 2.26.0.155, while the latest is 2.26.4.414. To get the latest C1WebForms, please uninstall the older ControlPanel and install the latest one from this link: https://cdn.mescius.com/ComponentOne/ControlPanel/ComponentOneControlPanel_226.4.414.exe
Once it is installed, you will find the latest version of C1WebForms in the ControlPanel:
→ what’s about my license key ? not changes anything about it ? using the same license key ?
The screenshot you shared shows a 2024v2 edition key. That key works with WebForms versions up to 2025v2 only, so it will not support 2026v1 (build 413), the version you are upgrading to. You will need to upgrade your license key to use the newer versions.
For a new license key or any related questions, please contact our Sales team:

I’ll contact to EU Sales.
I dont understand.
“In case you would like to still have updates, you just need to renew your perpetual subscription.
Perpetual means that you can use your key with no time limit, however, if you do not renew, you will not have access to support and newer versions.”
We have 2 licences, perpetual subscription licenses.
One year for updates ?
We pay 2 licenses in 2026 may. We use 2025v2.399 version.

We apologize for the confusion. The correct key version should be 2025v2 rather than 2024v2.
Therefore, we have generated the correct keys for you, which are perpetual and valid through 2026v2.
Please find them below:

Hello Enrique,
Thanks for confirming. Now that you have the updated keys for edition 2025v2, you can use any version up to 2026v2. That means you can move to version 2026v1 (build 413), the version you are upgrading to.
To activate the license on your machine, please follow these steps:
” in the top-right corner of the application.We shared the steps for updating to the latest version earlier, so please refer to that message for the upgrade itself.
If you run into any issues or have further questions, let us know.
