Yup, the license keys are for Aspose.Total, @andrey.potapov

22

@sudi.karmacharya,
Thank you for the confirmation. I’ve reproduced the problem with the license keys.

We have opened the following new ticket(s) in our internal issue tracking system and will deliver their fixes according to the terms mentioned in Free Support Policies.

Issue ID(s): SLIDESNET-44935

You can obtain Paid Support Services if you need support on a priority basis, along with the direct access to our Paid Support management team.

23

@sudi.karmacharya,
Could you please share the Order ID? We will try generating new keys for you.

24

Hi @andrey.potapov, is the issue with the keys?

Would the regeneration invalidate the existing keys? Would you like me to send it over privately?

Thanks,
Sudi

25

@sudi.karmacharya,
Unfortunately, I cannot answer your questions yet. We need to check your current order first. You can send it to my email.

26

Where can I find your email, @andrey.potapov ?

27

@sudi.karmacharya,
I’ve made this forum thread private. You can write your Order ID here.

29

@sudi.karmacharya,
Thank you for the information. I’ve forwarded it to our managers.

30

@sudi.karmacharya,
If you don’t mind, we will issue a license in the old format for you, and the existing one will be invalidated.
Alternatively, we’ll need 2–3 months to complete the switch to the new Metered API.

31

@andrey.potapov , I feel like I am out of sync here.

Why is a new license being issued at this time? What is the issue with the existing license?

Alternatively, we’ll need 2–3 months to complete the switch to the new Metered API.

What is the new Metered API, and how would that help with the issue in hand?

Thank you in advance.

32

@sudi.karmacharya,
We are currently experiencing some issues with metered licenses for Aspose.Slides. We had planned to update the Metered API (the issue you are experiencing will be resolved) but cannot do so shortly. So we offer to replace your license keys with others. Do you agree?

33

@andrey.potapov , yes please! that would be great.

34

In other news, authentication is also failing for Aspose Words starting yesterday for us.

Is the issue similar to Aspose.Slides? How can we fix this?

Thank you.

35

hi @andrey.potapov , we have paid support now. How can we migrate this issue to a paid support ticket?

36

@sudi.karmacharya,

One of our colleagues from Aspose.Words team will evaluate your issue for Aspose.Words soon. @alexey.noskov FYI.

If you have purchased Paid Support, then you may use the Paid Support account/credentials to login and raise the existing ticket (by referencing this thread) to paid support. To increase the priority of an existing issue from Free Support to Paid Support, it is enough to open a new Paid Support ticket using paid support credentials and paste the link to the Free Support Forum thread. There is no need to re-describe the issue. We will then analyze the issue, increase the priority accordingly, and continue to inform you about the ticket status on Paid Support Helpdesk. See the page on Paid Support FAQs and other policies for your reference.

Thank you so much. Appreciate that.

@sudi.karmacharya,
Our developers have investigated the case with the exceptions you described earlier (ticket SLIDESNET-44926).

Currently, there are two main builds of Aspose.Slides for .NET:

Aspose.Slides for .NET

This is the main version of the product. It uses the standard .NET graphics engine.

  • On non-Windows platforms, you may need to install the libgdiplus library.
  • Prior to version Aspose.Slides 25.4, for non-Windows platforms, it was necessary to use the .NET Standard 2.0 DLL from the Aspose.Slides ZIP package.
  • Starting from version Aspose.Slides 25.4, the NuGet package can be used directly even on non-Windows systems.
  • When running on non-Windows systems, your application must include the following line at startup:
AppContext.SetSwitch("System.Drawing.EnableUnixSupport", true);

Aspose.Slides for .NET6 CrossPlatform

This is the version of Aspose.Slides using a custom cross-platform graphics engine developed by the Aspose.Slides team.

On non-Windows platforms, the fontconfig library may be required.

Supported Platforms
  • Windows: x86, x86_64
  • Linux: x86_64
  • macOS: x86_64, ARM64
Planned for Future Support
  • Linux: aarch64 (ARM64) — ETA: end of 2025
Not Planned
  • Windows 11 ARM (ARM64) — Not currently under consideration

We hope this information is sufficient to close the issue. If anything else is required on our end, please let us know.

A bit more information about using System.Drawing.Common when running on non-Windows platforms.

The following native libraries are part of the Aspose.Slides for .NET6 CrossPlatform package.

  • aspose.slides.drawing.capi_vc14x64.dll
  • aspose.slides.drawing.capi_vc14x86.dll
  • libaspose.slides.drawing.capi_appleclang_arm64.dylib
  • libaspose.slides.drawing.capi_appleclang_x86_64.dylib

Could you please specify what problem you encounter with Aspose.Words? If possible, please provide code or step by step manual how to reproduce the problem and the exception stack trace if any.

Hey @andrey.potapov ,

Thank you for the explanation. Yes, please go ahead and close the SLIDESNET-44926 ticket.

Best,
@sudi.karmacharya

Hi @alexey.noskov,

I have a paid support ticket open for both Aspose Slides license key regeneration and Aspose words authentication failure.

Would it be best to move our conversation there?

For the time being, I’ll add the stack trace here and a code snippet for both.

Thank you,
@sudi.karmacharya
