Hi Pandaraboina, Rajesh,

Thank you for reporting the issue.

Based on the screenshot, the installation appears to complete most stages successfully, but fails while processing Microsoft.VisualStudio.Product.Professional during the finalization phase.

Can you open Visual Studio Installer and check whether Visual Studio 2026 Professional is listed. If it is, can you try to click More -> Repair.

Other than that I also see that you provide the location of the log can you help me share this file: C:\Users\rpandaraboina\AppData\Local\Temp\1\dd_setup_20260929155020_317_Microsoft.VisualStudio.Product.Professional.log

While the screenshot confirms that the failure occurs during the product finalization stage, it does not provide the detailed diagnostic information that led to the failure. The log file may contain additional error details that can help identify the specific operation that failed and determine the next troubleshooting steps.

If the required information is not available in this log, we may then need to collect the complete Visual Studio log bundle (vslogs.zip) for further investigation.

If you found my response helpful or informative, I would greatly appreciate it if you could follow this guide for your confirmation.

Thank you.

Hi @Pandaraboina, Rajesh

First try to repair the visual studio with admin privilege.
If not repair not helpful. uninstall visual studio and remove the temp files also. then restart your pc. install again visual studio.
During the installation deactivate the antivirus once done the installation reactivate.
Additionally check if any hadware issue exists in you system like RAM , MotherBoard, HDD issue. if its persists may be cause visualstudio wil fail.

please try the above solutions and give your feedback.
