Problems generating a Nios project

[Altera_Forum]

Hello everyone, 

 i got the DE0 evaluation Board and want to setup a Nios Processor. I´ve already build a nios system during my master thesis with the altera de3 board. I got the Nios processor setup in Quartus II 9.0 but when i want to open a project in Nios i get this error message:  1: The software settings (STF) file associated with this project is damaged. This may be fixed by copying your source files into a new C/C+ application project. For more details see the error log.  --> starting a new project in quartus leads to the same error message 2: Project cannot be created  Reason:  java.net.malformedURLException: unkown protocol: c  thanks in advance

I've spent hours on StackOverflow trying all these ccleaner (https://ccleaner.vip/) happy wheels (https://www.happywheels.vip/) vlc (https://vlc.onl/) complicated things and somehow found this and it worked. Thanks: )

i tried so many times. and i didnt face any type of issue like this. going for c/c+ is good but try some different app too vidmate (https://vidmate.ooo/).
