    Hi there,

    I just completed the activation of my office. I had bought 3 different softwares from Act in past 1 week.
    Its all geniune and work really fast. The activation process for office was a bit different, but that Office also got activated in 30 mins for me.

    Thanks to Act Software for this assistance.

  3. The license key worked for me
    I was skeptical at first as I was only provided instructions with a mail that said order processing. Even went as far ahead as to post a comment that said that the site was a scam
    the license key however was provide 30 hours later and worked like a charm
    So i can assure you that this site is not a scam

As I encountered difficulties activating my product due to an unexpected installation ID change, the prompt and effective assistance I received from the customer support team was invaluable. From the moment I reached out, I was met with instant replies and proactive guidance that swiftly resolved my issue.

  6. ActSoftware is prompt on their work. Within a few hours time the team responded. The installation worked out just fine

      You’ve got it perfectly right, sometimes it does not ask for a Confirmation ID.

    Was worried in the start and the support telephone number doesn’t work.. But in the end, everything was smooth.

    It worked like a charm, you will have to follow steps and patiently wait for the confirmation Id. It is genuine and I have performed a Microsoft Office update as well, it worked smoothly.

    Please follow steps as mentioned do not activate the key at Microsoft website, it is a CD driven license not an online license.

  9. They take some time to send the confirmation ID, but it works.
