SimpDelPatoJuan Posted August 22, 2022 Author Share Posted August 22, 2022 (edited) JVM info: Oracle Corporation - 1.8.0_341 - 25.341-b10 java.net.preferIPv4Stack=true Found java version 1.8.0_341 This is the log that appears when it fails, is this the thing you say?

Luis_ST Posted August 22, 2022 Share Posted August 22, 2022 The installer log is a file which is generated near to the installer. Quote Link to comment Share on other sites More sharing options...

warjort Posted August 22, 2022 Share Posted August 22, 2022 Looks like there is something wrong with your temporary folder configuration in your user's windows environment variables? It is trying to use "D:\Program Files (x86)" as your temporary directory, which is wrong. It obviously fails because you don't have the rights to create files there. Quote Boilerplate: If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one. If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install Large files should be posted to a file sharing site like https://gist.github.com You should also read the support forum sticky post.

SimpDelPatoJuan Posted August 22, 2022 Author Share Posted August 22, 2022 (edited) Then how could i fix it So when I open the installer it creates a temporary file but because i don't have permisson it doesn't create and thats why i can't open it?

warjort Posted August 22, 2022 Share Posted August 22, 2022 at java.nio.file.Files.createTempFile(Unknown Source) at javax.imageio.stream.FileCacheImageInputStream.<init>(Unknown Source) at com.sun.imageio.spi.InputStreamImageInputStreamSpi.createInputStreamInstance(Unknown Source) The temporary file it is trying to create is one used by java, not something created directly by the installer. From the name it looks to be something to do with "image caching". This link has some instructions on how to change your temporary folder: https://www.howtogeek.com/285710/how-to-move-windows-temporary-folders-to-another-drive/ But that is quite old, you might be able to find more up-to-date instructions somewhere else? You can always contact Microsoft support. It is very possible that the error is actually caused by some other problem with windows.

warjort Posted August 22, 2022 Share Posted August 22, 2022 Quote JVM info: Oracle Corporation - 1.8.0_341 - 25.341-b10 You could also ask Oracle since that is the java you are using.

SimpDelPatoJuan Posted August 22, 2022 Author Share Posted August 22, 2022 Okay ty very much Also what folder should i change it to? Quote Link to comment Share on other sites More sharing options...
warjort Posted August 22, 2022 Share Posted August 22, 2022 (edited) The default value is %USERPROFILE%\AppData\Local\Temp But you are really asking the wrong people. This is the forge support forums, we are not experts on MS Windows, even if sometimes think we are. 🙂 Edited August 22, 2022 by warjort Quote Boilerplate: If you don't post your logs/debug.log we can't help you.
