https://www.opera.com/computer/portable

I download the portable edition from the link and ran the portable setup file. It defaulted to "standalone installation" mode with "C:\Users\myusername\Desktop\Opera" as the install path. Then, I actually installed.

Install: C:\Users\myusername\Desktop\Opera
Profile: C:\Users\myusername\Desktop\Opera\profile\data
Cache: C:\Users\myusername\Desktop\Opera\profile\data

So, all good for me.

But I do not think that web address give me a portable version opera, maybe that is another bug of the website. Leocg, I think you can try to download from https://www.opera.com/computer/portable to tell that. If it was possible, will you please give me a directly URL to download the portable version opera. My OS is Win 10.

As you mentioned if the reason is due to the VPN, then all browsers should be affected, but the edge is OK as the attachment.
I have acrobat installed in my computer to read the pdf files, and it works fine.

We've encountered odd behaviors with pdf files and GPOs via VPN. If so, find the GPO .xml file and delete it. Reboot and try again. The .xml file may even be a legacy file from a previous VPN connection.

The GPO file may include something like this:

<Association Identifier=".pdf" ProgId="AcroExch.Document.DC" ApplicationName="Adobe Acrobat Reader DC" />

Do you have a pdf reader installed?

@leocg Yes, I did all the things like in the "https://forums.opera.com/topic/43601/instructions-on-posting-about-problems-in-opera-for-windows/2", but it still can not show pdf file correcttly.
My OS is windows 10 21H2 64 bit, the ver of opera is 87.0.4390.45.
The problerm web page link is "https://www.analog.com/media/en/technical-documentation/data-sheets/adl5580.pdf".
The screen-shot of the problerm is 1.jpg
BTW, when I drop a local pdf file to opera, it also can not show it's content correcttly.
But as I mentioned before, when I install the old ver 85.0.4341.18 of opera, it did well all about those pdf files.

I tried to install opera 87.0.4390.45 on a Win7 in a virtual machine, and it shows the same problerm. On the virtual machine the opera is the first time to be installed, so it should be a clean installtion.

I tried to uninstall the new version of opera, and install the old version , it works fine. But when I reinstalled the newer version, the problerm comes back again. Also what I found is that the 85.0.4341.18 is the last version which works well for me, any newer version can not show pdf correcttly.

But today the old version opera insists to notice me to "Get the latest security update", and I can not stop it. If there are some methods to stop this warning, so I can use the old version continuely? I have deleted the file "opera_autoupdate.exe"
