In early 2024, Vernier Science Education had a small but significant name change in its transition to a Perpetual Purpose Trust. As a result, the app signature had to change with the app update. In-app updates between app versions having different signatures is not possible. This is expected to be a one-time hiccup in updates to Spectral\u00a0Analysis.<\/p>\n<\/div>\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"850\" height=\"1024\" src=\"https:\/\/www.vernier.com\/til\/wp-content\/uploads\/sites\/2\/2024\/02\/SA-error-850x1024.jpg\" alt=\"\" class=\"wp-image-19075\" style=\"width:385px;height:auto\" srcset=\"https:\/\/www.vernier.com\/til\/wp-content\/uploads\/sites\/2\/2024\/02\/SA-error-850x1024.jpg 850w, https:\/\/www.vernier.com\/til\/wp-content\/uploads\/sites\/2\/2024\/02\/SA-error-498x600.jpg 498w, https:\/\/www.vernier.com\/til\/wp-content\/uploads\/sites\/2\/2024\/02\/SA-error-768x925.jpg 768w, https:\/\/www.vernier.com\/til\/wp-content\/uploads\/sites\/2\/2024\/02\/SA-error.jpg 1105w\" sizes=\"auto, (max-width: 850px) 100vw, 850px\" \/><figcaption class=\"wp-element-caption\"><strong>Update Error<\/strong><\/figcaption><\/figure>\n<\/div>\n<\/div>\n<\/div>\n<div style=\"height:10px\" aria-hidden=\"true\" class=\"wp-block-spacer\"><\/div>\n<h3 class=\"wp-block-heading\">Related Links<\/h3>\n<ul class=\"wp-block-list\">\n<li><a href=\"\/til\/19672\/\">Graphical\u00a0Analysis fails to update on Windows<\/a><\/li>\n<li><a href=\"\/til\/23945\/\">Instrumental\u00a0Analysis fails to update on Windows<\/a><\/li>\n<\/ul>","protected":false},"excerpt":{"rendered":"<p>This post pertains to Windows computers only.
