Hi, Trouble installing Bitdefender on my second device running Windows 7.

Hello.

On the same issue, check out this comment by @mrmirakhur :

If that didn't help, follow these steps:

First, take screenshot(s) of the issue(s) and create a log on your Windows device using Bitdefender Support Tool, by following these steps:

Next, contact Bitdefender Consumer Support by e-mail here (scroll down to the bottom of the page):

with short description of the issue(s).

After that, you will get an automated reply by the Bitdefender Customer Care Team, with your ticket number.

Now, in reply to that automated reply, you can send the screenshot(s) you already took and the log file you already created in the first step.

Since you are all done, just wait for the support engineers to investigate your issue(s) and find solution(s) to fix the issue(s).

Remember that the screeshot(s) and the log file will help a lot to the support engineers for better and faster investigation on your issue(s) and finding solution(s).
