      <description>&lt;P&gt;I fixed this by upgrading the version of .Net Framework on the server.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Retrospectively I have found that requirements for the January 2020 version of Power BI Report Server specify v4.7&lt;/P&gt;&lt;P&gt;see&amp;nbsp;&lt;A href="https://docs.microsoft.com/en-us/power-bi/report-server/system-requirements" target="_blank" rel="noopener"&gt;https://docs.microsoft.com/en-us/power-bi/report-server/system-requirements&lt;/A&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;This was not something mentioned on&lt;/P&gt;&lt;P&gt;&lt;A href="https://docs.microsoft.com/en-us/power-bi/report-server/upgrade" target="_blank" rel="noopener"&gt;https://docs.microsoft.com/en-us/power-bi/report-server/upgrade&lt;/A&gt;&lt;/P&gt;&lt;P&gt;which I was using to apply the upgrade.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;The server had v4.6.x.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I upgraded to v4.7.2.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;The installation now completes without error&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;What pointed me to the version of .Net Framework as being the issue was that I tried the install on a server which had an even older version installed (4.5.x from memory).&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;Running the install on that produced a message to say the version was too old.&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;I guess for some reason the install exe could not work out the version installed on the server I was having the problem with.&lt;/P&gt;</description>
