Whenever I run the installer for ANY of the products, I get an error message that the “installer integrity check” has failed. Here is a screenshot [http://simplechanges.us/wp-content/uploads/2021/03/Screenshot-2021-03-02-203847.png](http://simplechanges.us/wp-content/uploads/2021/03/Screenshot-2021-03-02-203847.png) Does anyone know of a solution for this. I have never had a problem with an installer on this machine. ---

Hi Doug, the certificate which we must use to sign our programs, doesn’t support XP any longer, you can’t install any products on this old, outdated and still unsupported OS. This is a security reason, sorry. Cheers Richard ---

Not sure why you think I’m on XP, nor why you are snarky about it. I am Windows 10, version 20H2 and I am PAYING for Navigraph Ultimate. Can I please have help in getting this to work. I would like to keep paying $$ for this service.

Ähm, sorry Doug I don´t understand you but read YOUR topic title … what do you mean than with “Installation Problems on with Win XP”? I have just tried to download the manager from our webpage and I can start the setup without any issues. So please try to re-download it (possible clear your cache, use an other browser, disable your anti-virus software for this download - if someone exist, and/or disable your firewall - if someone exist). ![image](https://europe1.discourse-cdn.com/flex013/uploads/navigraph1/original/2X/b/bd2ed3a539f2e018871066fa5ebb373156e75964.png) Cheers, Richard ---

Hi Doug, Lets start afresh. Please disable any Antivirus and firewall. If you have backups of previous AIRACs you wish to keep, backup c:\ProgramData\Navigraph\FMSClient\backup Use Windows to uninstall FMS Data Manager. Specifically: 1. Press Start and open Apps & Features. 2. On the right hand side, open Programs and Features. 3. Find Navigraph FMS Data Manager in the list, select it, and press the Uninstall button above. ![image](https://europe1.discourse-cdn.com/flex013/uploads/navigraph1/original/2X/1/10c2362800dcdaf9bc0d112798e5c2fe43de864e.png) If they exist, delete folders: c:\ProgramData\Navigraph\FMSClient and c:\Program Files (x86)\Navigraph\FMS Data Manager. Download and install latest [FMS Data Manager](https://www.navigraph.com/FmsDataManager.aspx). Please let us know how you get on. Cheers Ian ---
