The instructions worked well but just recently I tried using the same instructions on another computer and realised that running the TightVNC Web viewer using Chrome didn&#8217;t work. I spent hours trying to work out what the problem could be. I initially thought that maybe it was the computer I was using so I tried it on my laptop and had the same issue. Here&#8217;s what I kept getting when opening the viewer applet example.html file:<\/p>\n<p><a href=\"https:\/\/cdn.businesslegions.com\/blog\/wp-content\/uploads\/2015\/05\/TightVNC-Web-Java-Issue.jpg?strip=all&w=2560\"><img decoding=\"async\" class=\"alignnone wp-image-3417 size-full\" src=\"https:\/\/cdn.businesslegions.com\/blog\/wp-content\/uploads\/2015\/05\/TightVNC-Web-Java-Issue.jpg?strip=all\" alt=\"TightVNC Web Java Issue\" width=\"595\" height=\"219\" srcset=\"https:\/\/cdn.businesslegions.com\/blog\/wp-content\/uploads\/2015\/05\/TightVNC-Web-Java-Issue.jpg?strip=all 595w, https:\/\/cdn.businesslegions.com\/blog\/wp-content\/uploads\/2015\/05\/TightVNC-Web-Java-Issue-300x110.jpg?strip=all 300w, https:\/\/cdn.businesslegions.com\/blog\/wp-content\/uploads\/2015\/05\/TightVNC-Web-Java-Issue.jpg?strip=all&amp;w=119 119w, https:\/\/cdn.businesslegions.com\/blog\/wp-content\/uploads\/2015\/05\/TightVNC-Web-Java-Issue.jpg?strip=all&amp;w=238 238w, https:\/\/cdn.businesslegions.com\/blog\/wp-content\/uploads\/2015\/05\/TightVNC-Web-Java-Issue.jpg?strip=all&amp;w=357 357w, https:\/\/cdn.businesslegions.com\/blog\/wp-content\/uploads\/2015\/05\/TightVNC-Web-Java-Issue.jpg?strip=all&amp;w=476 476w\" sizes=\"(max-width: 595px) 100vw, 595px\" \/><\/a><\/p>\n<p>The error message was &#8220;This site uses a plugin (Java(TM)) that is unsupported. To troubleshoot the problem I tried a number of things. I tried reinstalling tightVNC which didn&#8217;t help. I then uninstalled Java and reinstalled it which didn&#8217;t work either. I then decided to reinstall Chrome and that didn&#8217;t fix the problem. I felt a bit frustrated so I decided to leave it for a few days and decided to come back to it&#8230; that was like a few weeks ago (yes I did forget about it).\u00a0For some reason, today I decided to give it another go.<\/p>\n<p>This time I paid a bit more attention at the issue. In the above screenshot you may not have noticed because I deliberately cropped the image but there is a Learn More button.

The button went to the following site:\u00a0<a href=\"https:\/\/support.google.com\/chrome\/answer\/6213033\">https:\/\/support.google.com\/chrome\/answer\/6213033<\/a><\/p>\n<p>In the article it mentioned that NPAPI plugins (what ever that is) does not work in Chrome version 42 and above. So that got me a bit curious so I decide to login to the machine that I originally used that had TightVNC Web Viewer working and low and behold it was using Chrome version 41. That&#8217;s why it was working!!! NPAPI worked on that version.<\/p>\n<p>Anyways as per the instruction the way to fix the issue it to enable NPAPI plugins and in order to do this:<\/p>\n<ul>\n<li>Open Chrome<\/li>\n<li>Type chrome:\/\/flags\/#enable-npapi<\/li>\n<li>Then press enable<\/li>\n<li><a href=\"https:\/\/cdn.businesslegions.com\/blog\/wp-content\/uploads\/2015\/05\/TightVNC-Web-Java-Issue-Fix-Enable-NPAPI.jpg?strip=all&w=2560\"><img decoding=\"async\" class=\"alignnone size-full wp-image-3420\" src=\"https:\/\/cdn.businesslegions.com\/blog\/wp-content\/uploads\/2015\/05\/TightVNC-Web-Java-Issue-Fix-Enable-NPAPI.jpg?strip=all\" alt=\"TightVNC Web Java Issue Fix Enable NPAPI\" width=\"657\" height=\"67\" srcset=\"https:\/\/cdn.businesslegions.com\/blog\/wp-content\/uploads\/2015\/05\/TightVNC-Web-Java-Issue-Fix-Enable-NPAPI.jpg?strip=all 657w, https:\/\/cdn.businesslegions.com\/blog\/wp-content\/uploads\/2015\/05\/TightVNC-Web-Java-Issue-Fix-Enable-NPAPI-300x31.jpg?strip=all 300w, https:\/\/cdn.businesslegions.com\/blog\/wp-content\/uploads\/2015\/05\/TightVNC-Web-Java-Issue-Fix-Enable-NPAPI.jpg?strip=all&amp;w=131 131w, https:\/\/cdn.businesslegions.com\/blog\/wp-content\/uploads\/2015\/05\/TightVNC-Web-Java-Issue-Fix-Enable-NPAPI.jpg?strip=all&amp;w=394 394w, https:\/\/cdn.businesslegions.com\/blog\/wp-content\/uploads\/2015\/05\/TightVNC-Web-Java-Issue-Fix-Enable-NPAPI.jpg?strip=all&amp;w=525 525w, https:\/\/cdn.businesslegions.com\/blog\/wp-content\/uploads\/2015\/05\/TightVNC-Web-Java-Issue-Fix-Enable-NPAPI.jpg?strip=all&amp;w=450 450w\" sizes=\"(max-width: 657px) 100vw, 657px\" \/><\/a><\/li>\n<\/ul>\n<p>Test by running the example file (viewer applet example.html) and see if the error message comes up.
