<p dir="ltr">Ciao Terry,</p>
<p dir="ltr">Ho avuto un problema simile con un altro plugin, poi risolto dallo sviluppatore.<br>
Credo tu abbia un carattere accentato nel percorso al file (nell'errore si richiama un carattere ASCII non codificato).</p>
<p dir="ltr">Spero sia utile.</p>

> Subject: [Gfoss] Viewshed analysis Plugin e ultime versioni di QGIS<br>
> Ciao a tutti,<br>
> qualche giorno fa ho voluto testare il Plugin Viewshed analysis seguendo un tutorial in rete; premetto che sul mio portatile ho Windows10 e che avevo installato contemporaneamente Qgis 2.12.3 e Qgis 2.13...(a causa di un aggiornamento non voluto fatto qualche giorno fa). Inoltre ho una virtualbox su gui ho installato OSGEOLIVE 8. <br>
> Nel tentativo di portare a termine l'esercizio correlato al plugin, dopo aver inserito tutti i dati richiesti veniva fuori un messaggio di errore:<br>

> Effettuando lo stesso test con QGIS 8.3 nella virtual box non si sono riscontrati problemi. <br>
> <br>
> Siccome qualcuno mi aveva detto che le nuove versioni di Qgis non sono così stabili ho fatto presente la cosa a coloro che hanno distribuito il tutorial e mi è stato risposto che c'è pericolo di instabilità se si mantengono sullo stesso PC versioni diverse di QGIS...(in effetti avrei dovuto provvedere prima a mantenerne una).<br>
> Oggi ho disinstallato le ultime versioni con OSGEO4 setup, ho ripulito il PC (non ho riavviato però...forse avrei dovuto), e ho installato solo Qgis 2.12.3 e GRASS 6.4.3 lasciando il resto inalterato.<br>
