If that does not work, hunt down other directories where QGIS files are found like in the user profile. You can also destroy the registry keys. You could also try with the other QGIS installer. Make sure you run the installer in admin mode. Ideas can be found here. This was for QGIS 2.x.</div><div dir="ltr"><br></div><div dir="ltr"><a href="https://gis.stackexchange.com/questions/152873/how-to-completely-uninstall-and-remove-qgis-2-8-1-on-windows-vista">https://gis.stackexchange.com/questions/152873/how-to-completely-uninstall-and-remove-qgis-2-8-1-on-windows-vista</a></div><div dir="ltr"><br></div><div dir="ltr">Nicolas</div><div dir="ltr"><br>Le 12 mars 2019 à 02:10, Jana Michalková <<a href="mailto:j.kormanikova@gmail.com">j.kormanikova@gmail.com</a>> a écrit :<br><br></div><blockquote type="cite"><div dir="ltr"><meta http-equiv="Content-Type" content="text/html; charset=utf-8"><div dir="auto"><div><div class="gmail_quote"><div dir="ltr" class="gmail_attr">Hello all,<br></div><div dir="ltr"><div dir="ltr"><div><br>
</div><div>I would need little help from you. One of my student has a problem with</div>
QGIS on Windows. After the last QGIS shutdown Windows got an error message <i>The code execution cannot proceed because qgis_app.dll was not found</i> (and another ones see below) and he can not run QGIS from this moment. He attempted to reinstall it, we also tried to use this <a href="https://anitagraser.com/2016/03/26/how-to-fix-the-windows-config-for-qgs-default-program/" target="_blank" rel="noreferrer">tip</a> and <a href="https://gis.stackexchange.com/questions/240159/qgis-2-18-the-program-cant-start-because-qgis-app-dll-is-missing-from-your-com/247194" target="_blank" rel="noreferrer">this</a>, but nothing worked. It still does not complete the installation and will not create icons on the desktop nor in the start menu. He tried to install different qgis versions (3.6, 3.4, 2.18, 2.18, 2.14). It worked only for version 1.xx.<br><div><br>
