@burnout426 Nope. I tried in my Desktop and the default one.

@burnout426. Unfortunately Opera still refuses opening.

Win 7 is a 32 bit system. I don't think there is a correlation to the user-account I use because there are no other signs of collision between softwares and administratorship. Moreover the first system which made problems was installed for any user. The problem lies deeper, maybe on the Windows side. I don't own a Microsoft account. I have the installation file 95.0.4635.84 of September 2023 stored. Since this is probably the version starting the problems I will try to find an older version. Anyway thank you for the advice.

Before my last post I thougt I had installed Opera 95.0.4635.46 with Setup.exe. The version I deleted via Windows program removal appeared as version 90. Maybe the Setup automatically took the newest version?? The I tried the 4561.50_Autoupdate.exe.
The installer had no question, I found the installation in the folder where I keep my older software installation files (on another disk partition). The program opened, funny that all the bookmarks I thought were deleted, appeared again. But it is not working properly. It claims a missing opera_elf.dll and asks for a manual installation. What was wrong with my clicking on Autoupdate? Clicking on a bookmark a prompt "side crashed, try again" appears.

@burnout426 Thanks for the informations. I followed the desinstallation advices including registry cleaning, and again installed version 4561 and afterwards 4635 with the same result. With the older version pages crash (not the internet connection, update data were collected without asking), with the newest clapping windows.

So Goodbye Opera (at least on this computer)
