Can download installation file (msi) but cannot run it.

I can download the msi file but I cannot run it. Error message: Windows cannot access specific device, file, or path. You may not have appropriate permissions to access them. I did receive: Your license was issued.
Your activation key is: 3d6febd1-78ef-4d27-921d-996b5b64093a

Hello,
this error can happen for several reasons but I would check your permissions in the first place. Then let me know if it helps. Thank you.

Permissions are fine - no problems.

Hi, are you using any Anti-virus? Try to disable it for a while and let me know if it helps. You can also try to download the latest version of eM Client from this link: http://www.emclient.com/dist/v5.0.175…
