Hi @kmeenakshi_26,
We're happy to welcome you to our Community! 🥳
First of all, please try to run the downloaded TeamViewer application as Administrator, as shown below:
As a second step, you can as well check if your antivirus software allows or blocks the installation of TeamViewer.
If you're still struggling to install it, could you please send us a screenshot of the error message?
I hope the first two steps will help you out. Otherwise, let us know to investigate further 🙂
Best,
Jen
