    Hello and Happy New Year.

    In a new installation of our application on a virtual machine windows server 2022 we get the following error. This only happens on one specific installation while on dozens of others on different clients it works without a problem. I believe it is caused by some setting in the windows system but I can’t figure out exactly what the problem is.

    Hello Manos,

    Happy New Year to you as well!!

    We tested the behavior with the mentioned version but could not replicate it with the following machine:

    Sample we used to verify: Editor_Sample.zip

    Could you please let us know if we are missing something here? Please update the attached sample or attach a stripped-down version of your project for further investigation.

    Furthermore, please use the latest version of the C1Editor (.NET Framework 4.8 2024v2) as the version you are using is out-of-support from our end. Currently, .NET FW 4.5.6, .NET FW 4.8, and .NET 6+ frameworks are supported.

    Also, if the behavior is confirmed to be a bug in the latest version as well, a fix will be available in the new releases only.

    Regards,

    Uttkarsh.

    Hello Uttkarsh

    I am running your example on the windows server where I have the problem and your example does not run either. I am attaching a screenshot of the error from the windows logs from your example.

    1920×1080 151 KB


    It runs without any error on different PCs. I can’t figure out what could be wrong with the specific PC that’s crashing.

    Regarding the upgrade of the version of component One, we should first see if the newest version is included in the license we have already purchased, otherwise we will have to purchase a new license.

    I believe that this particular error is not related to the specific version of component one but to some Windows server configuration on this particular PC because for many years now the same code has continued to run without problems in many installations at our different customers.

    However, could you send me the same example in the latest version so I can check if it runs on this particular machine before I proceed with any upgrade?

    What could be missing from Windows that affects the specific function that crashes?

    Thanks in advance.

    Hello Manos,

    Thank you for testing our sample and confirming the behavior.

    I believe that this particular error is not related to the specific version of component one but to some Windows server configuration on this particular PC

    We understand your concerns; however, we need to rule out the possibility of the behavior being a bug in the older version and ensure that it replicates with the latest version as well to escalate for further investigation.

    Regarding the behavior specific to your machine configuration, we have tried different scenarios, like changing the System Locale to “Greek”, using mentioned Windows Server version, etc. but could not replicate the behavior

    Please test the behavior with the attached latest sample and let us know your observations. (see Editor_Sample_Latest.zip)

    Regards,

    Uttkarsh.

    Hello Uttkarsh

    First of all thank you for your response.

    Due to I don’t have the latest license I can’t build the Editor_Sample_EmptyHtml that you send me.

    Could you please build it and send me the executable again?

    Thank you in advance.
