Dear Community, I want to install Pix4D on a new computer, however I need to download an old version because my Support & Updates expired Jan 22, 2020. Before I used version 4.5.6 on another computer without problem but when I go to [Pix4Dmapper technical release notes – Support](https://support.pix4d.com/hc/en-us/articles/115005738363-Pix4Dmapper-technical-release-notes) and click on 4.5.6 “new release” I get the following message: Your Support & Upgrade subscription has expired. You can only use up to version 4.4.12 of the software. Please check the license page for more details and extend your subscription. So I clicked on the “Download valid version” and installed 4.4.12 but now I cannot log in when I launch Pix4D mapper. The error message I get is: Error e0702d: Could not authenticate. Check your username and password. Can anyone help me on this? It cannot be a problem with the username or password because I could log in before when I had the new version. Best, ---

Hi, Welcome to the Pix4D Community. I just noted that all the links in the _release notes_ page, lead to the main download page. I created a download link for you with both PIX4Dmapper versions (4.5.6 and 4.4.12) [Download Link](https://pix4d365-my.sharepoint.com/:f:/g/personal/daniele_lecci_pix4d_com/EnQIJ90Wgv9NpUW5vmKV82oBm5A_JMkdy9xw_Vn-QgwN9Q?email=stlange%40awi.de&e=s2GSUk) Please let me know if you can download and use one of these version. Cheers Edit: Older versions can now be downloaded again from the release notes page: > **[PIX4Dmapper technical release notes](https://support.pix4d.com/hc/en-us/articles/115005738363-PIX4Dmapper-technical-release-notes)** > > Current version 4.8 > > > > Version > Release date > Release type > > > 4.8.2 > September 21, 2022 > Preview > > > 4.8.1 > July 5, 2022 > Preview > > > 4.8.0 > March 30, 2022 > Preview > > > > Disclaimer: The preview version contains n... ---
