Each Fotosifter license key is available for up to five computers, so if you have another computer, you can still activate it following the activation steps explained in the above question. If you have formatted your computer, you can also follow the activation guide to reactivate it.

If the installation was stuck at the very beginning, you can try the following method to see if this issue can be solved.

Method 1. Check whether the anti-virus programs on your computer have blocked the installation. If any, turn off the an-virus programs (e.g. McAfee), then install Fotosifter again and check if it works.

Method 2. Check whether the Ransomware Protection setting on your Windows 10 has blocked the installation. Win10 Ransomware project can prevent some of the programs on your computer from installing categories to the Documents folder. This may cause the installation failure as well as the project-saving failure. 

The steps shown underneath can help you disable Ransomware project:

Step 1. Use Win10 Cortana Search and input “Windows Defender Security Center“, find it and click to open.

Step 2. In the interface of Windows Defender Security Center, select Virus&threat protection.

Step 3. "Ransomware protection" is at the lower place.

Step 4. Click to turn it off. Then, install Fotosifter again.
